Also known as 'Center Post Weather Strip,' this adhesive strip will seal the drafty gap created between stationary and sliding glass doors when a panel pet door is installed. Available in black or white to accommodate differing door colors, the draft stopper is easily installed using the adhesive backing and fits all Endura Flap panels.
The adhesive strip is 1/2" wide and begins inset 1/8"—overall width is 1 7/ 8". If your door is higher than 96", purchase another 81" draft stopper and trim to the accurate size. Some customers use two—one at each end of the gap—for an even better seal. This energy-saving product is included in all Thermo Panel 3e, Quick Panel 3, and Thermo Panel 2e Microchip patio panels.
Step 1: Clean the area with rubbing alcohol where you are going to apply the draft stopper. This will allow it to adhere better.
Step 2: You can put the draft stopper on the back edge of the sliding panel, or if your sliding door is on the outermost track, you can put it on the front edge of the stationary panel. We recommend your draft stopper is installed inside and not on the outside where the weather can cause it to fail. If it is too wide, you can trim it, but be careful that the line is even, or else you will have gaps where air can get in. Also, you want the edge of the weather seal of the draft sealer to just barely kiss the glass. If you overlap, it will wear down the adhesive and will not stick for long.
Step 3: Start at the top, and as you are unrolling it, peel the covering off the self-adhesive as you work your way down. This method allows you to have more control to get a straighter installation of the adhesive backing.
Step 4: When you get to the door bottom, trim off any excess. Make sure there is no under-door draft blocker that will prevent you from opening and closing your door.
Note: Depending on the top and bottom tracks in order to get it to go the full length of the slider you might need to notch out small sections for it to fit inside the rails to completely cover the slider.

Can I paint the Draft Stopper?
We do not recommend painting it unless you use additional sealant since the paint can flake off when weather conditions make the rubber expand and contract.
Can I use weather stripping on the inside and on the outside?
Yes! This is a great solution for those in extreme weather conditions who need maximum insulation value.
Can I use this with a panel I already have?
Yes! It can be used with any of the Endura Flap panels, including window panels.
How wide is a strip of the draft stopper?
It covers gaps up to 1 ½” wide.
What do I do if my door is too short or tall for any of the sizes listed?
For any height less than 81" or 96", you can use a pair of scissors to trim the draft stopper to the desired length. For any sliding glass doors taller than 96", you can purchase 2 draft stoppers and trim the second one to fit the remaining height you need.
