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 No. 4 satin finish, which is a general purpose bright finish with a visible ‘grain” which prevents mirror reflection
• Removeable 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 allows the spring latch to remain in a retracted position, which allows access at any time.
• The economical cylinder locking device provides keyed access from the outside of the door.
