The Heavy Duty Dog Door is just that HEAVY DUTY. This door will stand up to the rigors of all types of kennels - professional gun dog kennels, boarding kennels, amateur kennels. This door has a die-cast aluminum frame; 1/4" clear Plexiglas and heavy-duty hinges. Just what you need to keep the cold air out in the winter and the insects out in the summer.

The only two-way dog door on the market with "special" heavy-duty spring-loaded hinges that provide a positive weather seal! When the dog goes out, the entire assembly opens up about the mounting bar's hinges. When the dog returns, the frame stays and only the acrylic panel passes through the wall/door allowing the dog back inside with the use of the hinges attached to the panel.

Chew Proof / Indestructible -

Developed by a Gun Dog Kennel owner/retriever trainer, Black lab tested for more than 20 years.

Energy Conservation / Insect Protection -

This door closes tighter than all other kennel doors due to the heavy-duty spring hinges specially designed for commercial use and abuse.

Easy To Install -

Only two 1-1/2-inch screws are needed.

The 12-1/2" x 17-1/2" opening of the Heavy Duty Dog Door is large enough for a dog over 120 pounds and the door swings easily enough to be operated by even 7-week black lab puppies.
