Type 304 stainless steel is well-suited for exterior weathering locations or interior hygienic locations such as hospitals and health care, pharmaceutical plants, research laboratories and food processing facilities. Stainless steel is corrosion resistant, durable and requires very little maintenance. Karp's stainless steel access doors have a No. 4 satin finish, which is a general purpose bright finish with a visible "grain" which prevents mirror reflection.

Removable doors allow for unobstructed access to wall or ceiling contents. To facilitate access and reduce door load, Karp can manufacture any size 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.
