Weld on swivel lock plunger for Series #30 casters. Lock caster movement at 90 degree angles with easy to use pull ring.
For use with Series 30 and Series 100 casters. Can be used on any caster forks with 4" x 4-1/2" top plate and lock notches on swivel.
Swivel locks instantly convert swivel casters to rigid ones. Just pull the ring, twist, and release for rigidity; pull and twist again to restore swivel. This feature greatly improves steering, especially for carts used in both tight spaces and long corridors.
