Security Boss Cable Bite Guard


Security Boss Cable Bite Guard for Guillotine Doors

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 the guillotine doors.

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

      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
