KRHA and KRHG Aluminum Karp Roof Hatches

Karp Associates, Inc. presents a re-engineered roof hatch that includes several new and improved features. Roof Hatches are available in galvanize model KRHG or aluminum model KRHA and are finished with EPA approved electrostatic paint. Karp's Roof Hatches now maintain heavy gauge stiffeners for added support and stability along with 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. All gasketing has been replaced with new wider and more durable gasketing to maximize the door/curb seal and ensure a watertight closure. All edges have been rounded for improved safety. Advanced assembly method allows for reduced welding blemishes.
