The compression attachment requires minimal tools and attaches without drilling into or compromising the curb of the hatch or your roofing membrane. Its grab bars are designed for safe and easy ingress and egress. The Hatch Defender is made of 1 ¼” sq. steel tubing, adjusts to fit virtually any size hatch and comes standard with a GuardDog Safety Gate.
