The lock includes a 6-pin C4 PD cylinder (LW5 profile) and is compatible with most restricted key systems. Finished in matte black, it provides a sleek, modern appearance while delivering exceptional durability. Fire tested up to 2 hours and cycle tested to 400,000 operations, it's ideal for heavy-duty use.
