Endura flap. Custom Thermo panel 3E.

We finally got our new enclosed patio done with three huge sliding glass doors. And then we added the enduro lap custom thermal panel 3Epet door. It arrived in good condition and went together easy and quick. I installed it myself insulation worked well. The only problem was to draft stop x2 was for a short glass door I believe 84 inches and needed to be for a 96 inch door so I called Pet doors and they shipped me one of two draft stops, hopefully they will send the second draft stop soon. We’re in Western Colorado and it gets cold here in the winter and hot in the summer and windy in the spring and summer. Two of the propers size draft will be necessary.

Quality product

Easy to put together and use. We install the panel when visiting my mother and remove when we leave. Works well and very convenient. Future consideration: install a sliding door locking mechanism on the panel with a spring loaded bottom section. Would be nice to install panel and lock to the existing sliding door locks.

Perfect

This was a great experience. We had ordered a custom dog door from our builder and after 3 months of waiting and no ETA on when they would have it done, I found this website and sent them the specs! The door arrived quickly and has been working for several months now!

Review

We just received the pet door week. The quality is far superior to our last sliding glass doggie door. it's much heavier/more solid, the glass is higher quality and better insulated, and the flap is both thicker and has a stronger magnet to keep it closed, even during high winds. Our sliding doors are oversized, custom, Pella doors, and we were concerned the pet door wouldn't fit properly. However, the fit was absolutely perfect, and we couldn't be happier. It was well worth the price.
