Security Boss Kennel Clad Dual Auto-Locking Premium Insulated Guillotine Door


Security Boss Kennel Clad Dual Auto-Locking Premium Insulated Guillotine Kennel Door

The First and Only Auto Locking Guillotine Kennel Door

Engineered to provide the ultimate in insulation and security, these guillotine kennel doors save customers money and provide security for the kennel occupants. These doors are built to withstand abuse while providing the best insulation & security possible. The guillotine door featues a 1" dense foam insulating core clad on both sides with 18 gauge aluminum sheets. The perimeter of the doors is framed with a reinforcing custom C-Channel that allows customers who have most previous kennel door versions to upgrade without new rails. All Security Boss products are hand-built to order.

Along the top of each guillotine door there is an offset fin/brush weather seal that covers the gap between the closed guillotine door and the wall, saving you on passive energy loss. The hidden floor seal is designed to make positive floor contact to eliminate gaps when the door is closed. The placement of this floor seal is hidden from destructive dogs to minimize any damage to the doors.  The Kennel Clad Insulated also uses the strongest side rails in the industry. This means no worries about warping or problems with your door gliding reliably when opening and closing. Not only will the insulating qualities of the Kennel Clad door provide for dramatic overall kennel energy savings, the rugged design will last for years. These doors will quite possibly be the last doors you will need to purchase.
