The KRP-450FR has a textured frame and bead so drywall joint compound can be applied in sufficient thickness to conceal the flange. The KRP-450FR is non-insulated for wall installation only and rated by Underwriters Laboratories for 1.5 hour “B” label in walls. 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. 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.
