The Klean-Lock Series, designed in compliance with Federal
Standard 209E, is listed by the National Sanitation Foundation and has been installed in
numerous FDA approved installations. Over our 112 year history, we have worked with
corporations with the most stringent clean spaces to ensure a clean environment when
manufacturing their products. Our unsurpassed design and fabrication standards result in a hermetically sealed product with minimal dependence upon gasketing material. Our EZ doorframe is the easiest troffer to maintain in the industry. When the fixture needs
to have lamps replaced, this doorframe does not need use screws so there is no danger of the seal being compromised due to human error. No tools are required to get into the fixture, saving money on maintenance.
