Security Boss Cable Bite Guard


Security Boss Cable Bite Guard for Guillotine Doors

Cable damage from resident dogs can be problematic. The Cable Bite Guard was developed to be an inexpensive, yet complete remedy for any facility. The Cable Bite Guard spans the entire width of the guillotine door - including the side rails. This simple design is secured into the wall on either side of the rails, providing a protective cover so that mischievous dogs cannot access the cables attached to the top of guillotine doors.

Designed to be universally adaptable to any Security Boss guillotine kennel dog door.

Heavy-duty 20 gauge aluminum is used in the fabrication of the Cable Bite Guard. Both the top and bottom are folded to give the unit strength, stability and a safe rounded edges to protect jumping dogs from injury. Each Bite Guard Protector is 20 inches tall so that you can position it easily to hide the cable connection point to the guillotine dog door. There are 2 standard sizes: the Regular Bite Guard spans a maximum width of 20 inches and the Large Bite Guard spans a maximum of 25 inches. Choose the model that easily will straddle your existing guillotine door and rail width.

    Bite Guard for Gullotine dog door Cables

    We have some rescue dogs that can bite through the heavy duty steel cables for the guillotine dog doors. We ordered these to see if it can prevent them from getting to the cables. We are very pleased with these. Our power chewer dogs have not been able to get to the cable and bite through it. If you are thinking of trying them please do the are well worth the money
