Security Boss 3-Sided Exterior Kennel Door


Security Boss 3-Sided Exterior Professional Kennel Door

Custom Made Energy Efficient Kennel Dog Door

The 3-Sided Exterior Dog Kennel Door is an energy-efficient exterior kennel door designed to cover the exterior of the kennel guillotine door to keep heat/cool in the building and prevent bugs and dirt from entering.  Featuring an energy-efficient exterior kennel door model that features a heavy-duty bi-directional hinge connection to the flexible vinyl flap. This hinge also uses weather stripping that protects the hinge from drafts and energy loss. These doors are popular among kennel operators that have high-energy dogs. The hinge flap connection allows the flap to move without tension. This full range of swing operation also allows larger dogs to use without the resulting pinching and wear that traditional flap connections offer. All Security Boss kennels doors are hand-built to order in the USA.


Each door is custom made to fit your kennel; simply provide the rough opening width and height.  To calculate your price, multiply width x height and select the matching size in our drop-down menu.
