Karp Associates, Inc. presents a re-engineered KRHG Galvanized Roof Hatch with several new and improved features. Karp’s roof hatches now maintain heavy-gauge stiffeners for added support and stability and an increased gauge of aluminum for greater durability and strength.

The exterior handle has been replaced with a push-button lock release located on the front side of the cover, shielded from environmental elements to prevent water accumulation and leakage. The gaskets have also been replaced with new, wider, and more durable gaskets to maximize the door/curb seal and ensure a watertight closure.

All edges have been rounded for improved safety. The advanced assembly method allows for reduced welding blemishes.

Roof hatches are available in galvanized steel KHRG Roof Hatch or aluminum model KHRA Roof Hatch and are finished with EPA-approved electrostatic paint.
