The Endura Flap Kennel Door is exactly like the original Endura flap door but excludes the parts that aren’t needed in applying a door to a kennel. Its common for dogs to have issues with using a rigid flap which is why the Endura is made to be flexible to prevent your dog from getting pinched in the dog should they backtrack while passing through the doorway. Now with a flexible flap chewing is more common and destructive so to prevent this you can mix some habanero chili pepper with Vaseline and smear it on the edges. This will make chewing on the flap undesirable and keep your dog from destroying the flap.
Some additional notes:
The Endura Flap™ Kennel door is intended to be installed in either a solid core wood door or in a wall that has been framed out. If you wish to install the Endura Flap™ kennel door in a hollow core door, you'll need to frame out the hollow core door first. Alternatively, you can use a regular Endura Flap™ pet door for doors which is "self-framing" though more expensive.
If you wish to install the Endura Flap™ Kennel Door in a wall and don't want to frame the wall yourself, you can purchase the Endura Flap™ dog door for walls in either single or double flap versions.
It has been our experience that the Endura Flap™ seals so well that the single flap model will meet most needs even in areas that experience four seasons. However, for really extreme weather, the door mount version and the wall mount version are both available in double flap models.
There is a significant difference between the rough cut out of the Endura Flap™ Kennel version and the regular Endura Flap™ for doors. The regular door mount cut out is larger to allow the bolts to fasten directly to the trim frame. The kennel version is smaller as we intend wood screws (not included) to be used to fasten the frame directly to the door or wall. The kennel door itself should be used as a template or use the rough cutout dimensions given below.
