- The 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 provides access at any time.
- Masonry straps secure the installation of Karp’s doors in masonry application.
- Type 304 stainless steel is well-suited for exterior weather or interior hygienic locations such as hospitals, 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, a general-purpose bright finish with a visible ‘grain” that prevents mirror reflection.
