RCF AC-4CASTER-SET-LOCK

Set of four locking casters for RCF subwoofers (excludes 12 inch and 15 inch models), built from zinc-plated pressed steel with a swivel housing and plate fitting. Each caster uses a double ball race and a 100mm (4 inch) wheel with roller bearings for smooth movement, with a lock to keep the subwoofer stationary when needed.
