KATR Access Door Options
- Type 304 stainless steel is well-suited for exterior weather 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” that prevents mirror reflection
- Removable doors allow for unobstructed access to wall or ceiling contents
- A 1/16″ x 3/8″ neoprene gasket can be added to the door, providing a tighter seal between the door and the door frame, adding protection from exposure to outside elements.
KATR Access Door Locking and Latching Options
- A cylinder locking device provides keyed access from the outside of the door. The night latch also has a small thumb latch that keeps the spring latch retracted, allowing access at any time.
