Karp Associates, Inc. presents a re-engineered KRHG Galvanized Roof Hatch with several new and improved features. Karp’s roof hatches now include heavy-gauge stiffeners for added support and stability, plus a higher-gauge 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. Karp Associates replaced the gaskets with newer, wider, and more durable ones to maximize the door/curb seal and ensure a watertight closure.

The Karp Associates team rounded all edges of the KHRG Galvanized Roof Hatch to enhance safety. Additionally, the advanced assembly method reduces 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.
