The panels on the PlexiDor PD DOOR XL and PD WALL XL units are manufactured using a solid 3/8 inch sheet of plexiglass instead of the thermo-pane panel design. This makes the panels virtually indestructible for larger dogs up to 220 lbs. The panels also come equipped with factory installed chew proof aluminum trim around all four edges and on both sides of each panel. This prevents damage to the panels from chewing which sometimes occurs with larger breeds of dogs (e.g. Labradors).
For chewing dogs smaller than 100 lbs., choose the PlexiDor PD TS Top Swing
