Product Details
The Draft Stopper Center Post Weatherstrip for Panels is designed to eliminate drafts and improve energy efficiency for sliding glass doors and patio panels. Perfect for use with panel pet door installations, such as doggie doors, this weatherstripping helps you maintain a comfortable and stable indoor temperature.
Our sliding glass door draft stopper is available in black or white to match your door's color, and it's easily installed using the adhesive backing. The trim-to-fit design allows you to choose lengths of 81" or 96" to ensure a custom seal for your door. If your door is higher than 96", simply purchase another 81" draft stopper and trim it to the accurate size.

FAQ
What does this do?Also known as the "Center Post Weather Strip", it seals the gap created between stationary and sliding glass doors when a panel doggy door is installed. So it will seal the draft between the sliding glass doors and provide better insulation when your pet door is installed. Please note that this is not the same thing as weatherstripping, which can also improve the insulation value of your pet door. |
Can I use one on the inside and one on the outside?Yes! Some of our customers in more extreme climates do so to ensure maximum insulation. |
I only see choices for 81" and 96" - what happens if my sliding glass door is not included in those ranges?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 example, if your panel is white and your sliding track is 75" then you would get the draft stopper 81" in white. For any sliding glass doors taller than 96", you can purchase 2 draftstoppers and trim the second one to fit the remaining height you need. |
How wide is the draft weather strip?The draft stopper covers gaps up to 1 1/2" wide. |
The gap on my door is less than that. What do I do with the excess that hangs off the side?You can trim the Endura Flap Draft Stopper Center Post Weatherstrip to the desired width as well. |
Does this work the same way with sliding windows?Yes, you can apply it the same way to the back edge of the stationary window. |
What colors does this come in?Black and white. |
Can I paint it?It is not recommended unless you use an additional sealant as the paint may flake off once the rubber expands and contracts due to weather conditions. |
Can I use this with a panel I already have?Yes, this patio door draft stopper or center-post weatherstrip is extremely versatile and can be used with any model of slider or window panel. For maximum insulation value, we suggest using this with one of our recommended extreme weather pet doors. |
Is the 81 in white the same as the Bug Warden - 81 in white?No, they are the same color and same length, but are used for different applications. |
I ordered an Endura Flap brand panel - should I buy this?We've included one draft stopper in all Thermo Panel 3e so unless you need another one, it is not necessary to purchase another! |
Can this weather stripping for sliding glass doors be used on my screen door?It is not recommended for that application. The Bug Warden is designed to allow your dog to use their door and have the screen door open for ventilation. |
How to fix drafty sliding glass doors is my problem, can you help?Yes, the Draft Stopper is designed to seal the gap between the operational panel and the fixed panel. It is easy to apply with a self adhesive strip. |
