Cylinder Lockers from Justrite offer superior features that make them extremely durable and easy-to-use. Constructed of 100% welded aluminum, they will not rust, corrode or discolor. Justrite’s expanded .065" (1.65mm) thick metal panels are the strongest in the industry – offering additional resistance to tampering. Welded security lug on front panel door accepts a padlock (not included) for extra protection. Heavier gauge aluminum mesh and extruded (not bent) frame add rigidity. All models have an exclusive solid aluminum roof panel that slants toward the back to shed water and ice.
