Simply the best
This is our second Hale pet door. Although not the least expensive, it certainly is the best. Excellent materials and construction with perfect fit are what lead me to this conclusion. We have the medium size for our two Springers. When we moved to our new home, it was a few months until I replaced our all glass porch door with one that has space for a pet door. Now that it is in, I'm not sure who is most delighted, my wife and I or our two Springers. The double door system is very effective in the winter keeping out the cold. The magnetic catches always secure the flaps perfectly after every entry or exit.
