KRHA - Aluminium Roof Hatch

Karp Associates, Inc. presents a re-engineered roof hatch that includes several new and improved features. 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. Roof hatches are available in galvanize model KHRG or aluminum model KHRA and are finished with EPA approved electrostatic paint.

Product Options for KRHA

Locks and Latching

This cylinder locking device provides keyed access from the outside of the door. The night latch also has a small thumb latch that allows the spring latch to remain in a retracted position, which allows access at any time.


Aluminum is ideal for any installations or evironments that require a strong, lightweight and rust-resistant access door.


To facilitate access and reduce door load, Karp can manufacture access door in a double leaf style.

A 1/16" x 3/8" neoprene gasket can be added to the door providing a tighter seal between the door and door frame, adding protection from exposure to outside elements.
