Mason Company offers the Pickwick 'Dog Operated Door'.
This is a Very strongly built two-way pet door. The outside frame is 5/16" thick solid cast aluminum. The inside swinging door is 1/4" thick polycarbonate. Spring hinges are plated to resist corrosion.
These are primarily used in kennels and often in conjunction with the Kenl-Dor. In that case, the Pickwick door provides for insulation and the Kenl-Dor is used to lock and unlock the opening.
The Min-Max dimensions specify a minimum and maximum opening that the pet door fits over. The entire assembly swings open when the pet is coming out. Only the inside polycarbonate panel swings inward when the pet goes back in.
No provision is made for locking (may be used in conjunction with the Kenl-Dor). Not recommended for cats. In fact, there have been cases where this door was used successfully to let the dog out while keeping the cat in!
Noisy when closing. Installation in a wall or hollow-core door requires framing. Requires a 2" minimum threshold.
Outside frame dimensions do not include the shims. You can see these in the graphic above. They are included with the kennel door.
Ground Delivery Only.
