3-Sided Exterior

Exterior frame for kennel doors

3 sided exterior professional kennel door

The 3-Sided Exterior Professional by Security Boss Manufacturing LLC uses a heavy duty stainless hinge with weather seal connection for the flap. This design works well for kennels that may house larger breeds at times or have anxious high energy dogs. The hinged flap design allows the flap to travel freely without any pinch point. This means your flaps will wear longer in diverse situations. Our heavy duty hinge also features a weather seal that minimizes drafts through the hinge.

The 3-Sided Exterior Kennel Door is made with a heavy-duty extruded aluminum, and has double reinforced mitered corners for structural strength. The flap is UV protected and has embedded nylon cords that run vertically in the material,. These flaps are also weatherized to prevent shrinking in sub-zero temperatures. Each flap has 1 1/2" long Alnico #5 magnets located on the sides that create a positive seal. (The number of magnets will vary depending on the size of the door being made). Both sides of the flap are also lined with heavy density brush weatherstripping to prevent any drafts. The flap length is 3/16" shorter than the sides of the door to minimize any scraping or wear due to movement on the kennel floor. The 3-Sided Exterior Professional doors are designed to be installed on the exterior side of the wall, allowing for full use of the interior mounted guillotine doors. When used together, you have controlled access along with unparalleled energy savings. Wall penetrations can vary greatly from facility to facility. Therefore our doors are custom made to the required dimensions.


Custom Made Energy Efficient Kennel Dog Doors


Product Note:The 3-Sided Exterior Professional uses a heavy duty hinge that connects the flap to the door frame. This model using the heavy duty hinge is typically recommended for kennels that incur high use as well as those that may house larger or high energy animals.

Note: Doors are non-refundable as they are built to your requirements.

Three sided opening are common in kennel facilities. These types of openings allow the operator to easily hose out / clean the individual pen area by washing debris outside of the building. Often these openings are specified by the architect in the early planning stages.

We encourage both owners and architects to contact us at the earliest phase of planning the facility to discuss possible options for kennel doors that would work best for the facility. We have a kennel consultant that can be contacted for kennel design free of charge.
