Manufactured with the highest quality materials, the Corbin Russwin CL3100 Series, Grade 1 Lever Locks guarantee strength, reliability and quiet operation.

Designed to meet the current increase in security needs, the CL3300 series offers several key features. All functions feature the Lever Release™ design for vandal resistance, allowing the outside lever to rotate when in the locked position.
