Important Information about Custom Heights

Custom orders are final sale. They are essential in two situations:

While most sliding glass door track heights are in the three standard height ranges offered, some are not. In those cases, we can build a Quick Panel 3 in a custom height to fit your specific dimension. 

The second situation is when you have a sideways sliding window. A sliding window is essentially a miniature sliding glass door, and you can install a custom height undersize Quick Panel 3 to fit, provided the window track width is at least 1" thick.  

 

Custom Height Minimum & Maximum Heights

Small  35" 100"
Medium  42" 107"
Large  48" 117"

Please read instructions & notes thoroughly before installation.

One-Piece Panel

Step 1: Step Over Adjust the Step Over (Optional)

  • The Endura aluminum sliding door panel has a patented Adjustable Step-Over feature which allows you to adjust the height of the flap to the most comfortable fit for your pet.
  • The top of the flap should be positioned to be at least 1” above the top of the pet’s shoulder.
  • If the factory setting is not suitable, please adjust it before proceeding. If the current setting is suitable, proceed to the “Installation Instructions” section.

Step 2 Adjust the Screws

  • Lay the entire panel on a flat surface.
  • Using a #2 Philips head screwdriver, remove the bottom side-screws and loosen the upper side-screws. Screws were tightly installed to hold the panel together during shipping; a power tool* is recommended.
  • If you do not have a Phillips head drill bit skinny enough to fit, let us know and we’ll send you one for free.

Step 3 Adjust the Spacers

  • Once the bottom screws have been removed and the upper side-screws loosened, the Pet Door Assembly and spacers can be removed by sliding the sections down and out of the panel.

Step 4 Replace the Spacers

  • Replace the spacers and the Pet Door Assembly by sliding them back in a different order to achieve the desired height. You can move the spacer below and above the flap to raise or lower the flap height.
  • The order of the pieces is important! The piece on the bottom needs to always be at the bottom, as that is where the screws attach.
  • Make sure that the locking cover side of the flap frame is on the same side as the height adjustment locks.

Step 5 Tighten the Screws

  • When finished, replace the bottom side-screws and tighten the next upper-side screws.
  • A lower step-over height is easier for pets to navigate. However, if the top of the flap is low enough that the pet needs to crouch to get through their pet door, they can injure themselves and possibly cause the pet door to malfunction. If your pet door does not sit at a comfortable height for your pet, you may need a larger flap size.

Step 1: Install the Panel Spring Mechanism

  • Loosen the height adjustment locks at the top of the pet panel. This allows the spring mechanism to move freely up and down.

Step 2 Test Fit the Panel in Your Track

  • You want to put the pet door in your track before applying any weather stripping to ensure it fits. If the panel fits well, proceed to the next step. See the FAQs if you have trouble.
  • To insert the panel into the top track, push up against the spring mechanism and swing the bottom of the panel up and over the threshold.
  • Seat the panel on top of the small guide rail in the track.
  • If you can’t quite get it in the track, try swinging in from the outside as the outside track wall may be shorter.

Step 3 Apply the Weatherstripping

  • Once you’re sure the panel fits, remove it from the frame and lay it on its side on the ground.
  • Apply the foam weather-stripping by peeling back the paper and exposing the adhesive.
  • Unroll it along the edge of the panel, pressing to ensure it adheres. Install on both sides, trim it fit with scissors.

Step 4 Install the Draft Stopper

  • The center post weather seal strip (draft stopper) should be installed on the inside of the home.
  • It can install on either the back edge of the sliding door panel or the leading edge of the stationary panel.
  • This strip prevents air from leaking between the sliding glass door and the stationary panel.
  • Trim with scissors as needed. Clean the edge of your patio door with rubbing alcohol before installing to assure a good seal.
  • Repeat step two to install the panel in your track.

  • The Endura aluminum sliding door panel has a patented Adjustable Step-Over feature which allows you to adjust the height of the flap to the most comfortable fit for your pet.
  • The top of the flap should be positioned to be at least 1” above the top of the pet’s shoulder.
  • If the factory setting is not suitable, please adjust it before proceeding. If the current setting is suitable, proceed to the “Installation Instructions” section.

Step 2 Rearrange the Pieces

  • Simply slide the pieces up and out from the bottom half of your panel to rearrange.
  • Loosen a bottom screw if the pieces are too snug to move.

Step 3 Reconnect the Pieces

  • Replace the spacers and the Pet Door Assembly by sliding them back in a different order to achieve the desired height.
  • You can move the spacer below or above the flap to raise or lower the flap height.

Step 4 Screw the Pieces Together

  • The order of the pieces is important! The piece on the bottom needs to always be at the bottom, as that is where the screws attach. You can now assemble the patio panel!

Step 1: Connect the Sections Align the Connectors

  • Align the aluminum connectors extending from the bottom flap panel section with the top glass panel section.
  • Press the aluminum connectors into the holes at the bottom of the top glass panel section.
  • Ensure locking cover & height adjustment locks are on the same side!

Step 2 Tap the Pieces Together

  • Gently tap the bottom surface of the panel against the ground to completely insert the connectors.
  • Protect hard surfaces to prevent scratching.
  • The components of the panel are designed to slide together very tightly.

Step 3 Secure the Sections

  • Fasten the two panels together using the four flathead screws and countersunk washers found in the panel packaging.
  • Use the included flathead screwdriver to tighten flathead screws and countersunk washers so the two halves of the door are pulled together.

Step 1: Install the Panel Adjust Spring Mechanism

  • Loosen the height adjustment locks at the top of the pet panel. This allows the spring mechanism to move freely up and down.

Step 2 Test Fit the Panel in Your Track

  • You want to put the pet door in your track before applying any weather stripping to ensure it fits. If the panel fits well, proceed to the next step. See the FAQs if you have trouble.

Lock Details

a lock can secure your slider in place

Since you cannot lock your sliding door to your panel pet door, we have provided you with alternative locking methods to secure your home:

Installing the sliding door clamp: This clamp has a screw that tightens by hand to prevent the sliding door from moving beyond the clamp’s placement. For doors manufactured with the glass slider on the inside track, the lock can usually be installed on the door’s raised track.

If you aren’t able to use the lock that comes with the panel: A great alternative to locking your sliding glass door is a Charley bar or dowel in the track. Both work off the same concept – they block the slider from opening. When engaged you cannot pull the sliding door away from the pet door panel.


use a charley bar or dowel in the slider track to secure your door

Other Installation Options

Semi-Permanent Installation:

You might choose to secure the panel in your track with screws. This can be done by drilling screws at an angle in the top and bottom tracks. We recommend doing this from the outside to minimize damage to the sliding glass door frame. One-way screws will prevent tampering or removal of the panel from the outside.

you can screw your panel into your slider for a more permanent installation

Stationary Panel:

Some stationary sliding door panels can be unfastened and moved over to one side so that you can install the pet door panel between the jamb and stationary panel.

Avoid damaging your sliding glass door by checking that your door can move and that you can reinstall it properly before trying to uninstall the unit.

You will still lose space in your slider to move through, however, you will be able to use your existing sliding door lock to secure your home. Installing your pet door this way is also great in that you already have an alarm system in place.

If your sliding glass door slides on the outside track, using an alternative lock might not be possible, so this allows you to still lock your door.

NOTE: You can do the stationary panel install with the regular spring actuator method – no need to screw it in.

FAQ

Does this panel work with vinyl sliders?

Yes, the Endura Flap Quick Panel 3 will work for vinyl sliding glass door so long as the track is at least 1" thick. However, for a snug fit and aesthetic look in your vinyl slider track, we carry the Vinyl Sliding Glass Pet Door as well. Read about the differences between vinyl and aluminum pet door panels here.

How do custom orders work?

The Quick Panel 3 is built with a 3" spring-loaded height adjustment. When you order in one of the custom height ranges, you will be prompted for your track height. The patio panel will be built to a height that is approximately in the middle of this 3" range. For example, if you specify 40", your panel will be built to adjust from about 38" to 41" tall.

How long do custom orders take to ship?

Custom orders cannot be resold. Therefore, they are final sale once built. Note that the glass units for custom height orders take one to two weeks for delivery from the tempering plant and that we need about a week to schedule the assembly after the glass unit arrives. So, even though your custom order must be pre-paid, delivery will take 2-3 weeks depending upon your location. (Stock items are not paid for until they are shipped).

How do I measure my door to get the correct height adjustment size?

Measure from the innermost part of the bottom track to the innermost top part of the track. If there is a pencil railing, include that in the measurement because the panel straddles the railing.

Does the Quick Panel 3 require tools for installation?

Endura Flap sliding glass dog doors under 80 ¼" do not require tools, making them one of the best dog doors for rental homes. Panels above this height will be shipped in two pieces and require some tools for installation. The sectionals will need to be assembled with 4 hex screws and a hex wrench, all of which are provided.

Can an intruder remove the panel from the outside?

No, the thumbscrews are on the inside of the panel, so once installed, the Endura Flap Panel can't be removed without first loosening the thumbscrews from inside the home.

Is this door good in a cold winter climate? I want something effective in our winter months.

Yes, the Endura Flap has been tested at -40°F and it withstands winds up to 50mph.

What Is the Step-Over?

The step-over is the part of the panel under the actual flap opening. Depending on the flap size purchased, the step-over can range from 3" to 7", so you can adjust it to any step-over within that range.

How thick is the panel?

The Quick Panel is 1" thick.

What locking mechanism can I use for the Quick Panel 3?

This door comes with a C-clamp lock. Alternatively, a wooden dowel or Charley Bar can be used for additional security.

Will there be enough room for me to get through after the panel is installed?

The panel will take up some space in your sliding door track. See the "Overall Panel Width" column in the size chart. This gives the width of the panel, which is the amount of space that will be taken up.

Warranty

Endura Flap products have a lifetime warranty against defects in materials and workmanship under standard regular use. Damage caused by not using the product as intended, improper installation, and chewing is not covered under this warranty.

Darth t.

he knows what he loves

Darth is our 115lb Malamute. 3 years ago we moved into a townhouse with a sliding door to the yard. Lots of research later I decided this door will be robust enough for Darth. In 3 years he has only managed to break one single screw from the flap panel, and he is not gentle with this door at all! The door and the rigid flap has held up spectacularly! The dog and 2 cats use it continuously. Recently we got a tiny 6lb dog and this door is too tall for him, so we got him a door his size and slid it into the sliding door next to this XLL one. Now the entire sliding door is full, and finally also secure, nobody can get in or out. My pets will never be without a door again (Posted on 5/3/2015 at PetDoors.com)

Yes, the Endura Flap Quick Panel 3 will work for vinyl sliding glass door so long as the track is at least 1" thick. However, for a snug fit and aesthetic look in your vinyl slider track, we carry the Vinyl Sliding Glass Pet Door as well. Read about the differences between vinyl and aluminum pet door panels here.

How do custom orders work?

The Quick Panel 3 is built with a 3" spring-loaded height adjustment. When you order in one of the custom height ranges, you will be prompted for your track height. The patio panel will be built to a height that is approximately in the middle of this 3" range. For example, if you specify 40", your panel will be built to adjust from about 38" to 41" tall.

How long do custom orders take to ship?

Custom orders cannot be resold. Therefore, they are final sale once built. Note that the glass units for custom height orders take one to two weeks for delivery from the tempering plant and that we need about a week to schedule the assembly after the glass unit arrives. So, even though your custom order must be pre-paid, delivery will take 2-3 weeks depending upon your location. (Stock items are not paid for until they are shipped).

How do I measure my door to get the correct height adjustment size?

Measure from the innermost part of the bottom track to the innermost top part of the track. If there is a pencil railing, include that in the measurement because the panel straddles the railing.

Does the Quick Panel 3 require tools for installation?

Endura Flap sliding glass dog doors under 80 ¼" do not require tools, making them one of the best dog doors for rental homes. Panels above this height will be shipped in two pieces and require some tools for installation. The sectionals will need to be assembled with 4 hex screws and a hex wrench, all of which are provided.

Can an intruder remove the panel from the outside?

No, the thumbscrews are on the inside of the panel, so once installed, the Endura Flap Panel can't be removed without first loosening the thumbscrews from inside the home.

Is this door good in a cold winter climate? I want something effective in our winter months.

Yes, the Endura Flap has been tested at -40°F and it withstands winds up to 50mph.

What Is the Step-Over?

The step-over is the part of the panel under the actual flap opening. Depending on the flap size purchased, the step-over can range from 3" to 7", so you can adjust it to any step-over within that range.

How thick is the panel?

The Quick Panel is 1" thick.

What locking mechanism can I use for the Quick Panel 3?

This door comes with a C-clamp lock. Alternatively, a wooden dowel or Charley Bar can be used for additional security.

Will there be enough room for me to get through after the panel is installed?

The panel will take up some space in your sliding door track. See the "Overall Panel Width" column in the size chart. This gives the width of the panel, which is the amount of space that will be taken up.

Darth t.

he knows what he loves

Darth is our 115lb Malamute. 3 years ago we moved into a townhouse with a sliding door to the yard. Lots of research later I decided this door will be robust enough for Darth. In 3 years he has only managed to break one single screw from the flap panel, and he is not gentle with this door at all! The door and the rigid flap has held up spectacularly! The dog and 2 cats use it continuously. Recently we got a tiny 6lb dog and this door is too tall for him, so we got him a door his size and slid it into the sliding door next to this XLL one. Now the entire sliding door is full, and finally also secure, nobody can get in or out. My pets will never be without a door again (Posted on 5/3/2015 at PetDoors.com)
