Corbin Russwin CL3120-NON-KEYED Grade 1 Privacy Cylindrical Lever Lock with T-Zone Vandal Resistance

Commercial-Grade Privacy Lockset Engineered for High-Traffic Applications

The CL3120 is manufactured from steel with zinc dichromated corrosion resistance, and its T-Zone construction has been tested to over 15 million cycles—exceeding ANSI/BHMA Grade 1 standards by 15 times.
