Ordering Instructions

Step 1: Prior to proceeding, thoroughly read the contents of this product listing and complete rough measurement estimates of your glass pane and pets to ensure this glass replacement with pet door will be the correct solution for your home and pets (short-legged pets may find the step-over too tall as the step-over will elevate your pet door 3 ¾ inches more off the ground).  If you have any questions about sizing, please reach out to our Customer Service at customerservice@enduraflap.com or by phone (800) 826-2871.

Step 2: Hire a glazier to measure the width, height, and thickness of the entire pane of glass that the custom-made unit will replace.  They should review the detailed instructions page for more specific instructions. Ask your glazier to determine if you have Low-E, clear glass, or tinted glass.  They may be able to help you fill out the order form.

Note: It is crucial that these dimensions are accurate since there are no standard sizes.  All Pet Door Guys In the Glass units are custom-made which means they are not returnable and are non-refundable.

Warning: Thermo-Tru brand sliding glass doors require a specialized glazier for installation. Make sure you do not have a Therma-Tru pet door before purchasing. 

Step 3: Place your order on the website and pay for your pet door.  Exact pane dimensions are not entered when you are choosing from the dropdown options on the website.  Standard glass is up to 34" wide x 76" tall and oversize glass is up to 34" wide and from 76" to 92" tall.  Once you place your order, you'll receive an order confirmation email with an orange "Finish Your Order" button to take you to the order form to provide the exact measurements from your glazier (explained in the next step).

Step 4: Complete the order form.

A. Clearly write or type the shipping address in the desginated space.  Standard size glass (up to 34" wide x 76" high) can be shipped to a residence and oversize glass (up to 34" wide and from 76 to 92" high) must be shipped to a business (non-residential) address.  

B. Write in the Quantity. Based on the glass information provided by your glazier, complete the Glass sections.  Select Glass Thickness.  Clearly write or type in the Width and Height of your actual glass (not visible glass) and lastly, select the Glass Type for your custom pane.

Note:  The minimum glass size allowed can be determined by your desired flap size:  add 6" to your desired flap size's width and add 7" to it's height.

C. Complete the remaining sections of the form.  Select flap size (reference this measurement guide), frame color, additional step-over height, and Pet Door Opening. For the Pet Door Opening review the instructions.  The X represents where the pet door is placed as if you are standing outside your home and looking inside. 

Note: Due to the pet door frame thickness, if the sliding glass door slides inside the fixed/non-operational panel, the pet door must be installed on the sliding glass door.  If the slider slides outside the fixed/non-operational panel, the pet door must be placed on the fixed piece of glass.  

D. Email the Order Form to customerservice@petdoors.com. Your order will be on hold until we receive this information. Please refer to our full set of instructions.
