Hamilton General Service 3 1/4″ Swivel Casters

General Service 3 1/4″ Swivel Casters manufactured by Hamilton

Series GS is constructed from swivel parts “cold forged” under a 1,000 ton press, a process that rearranges the molecular structure of the steel to provide greater density at points of stress. Mirror-smooth double ball raceways are the result of coining under extreme pressure, and then hardening for long life. Zinc plated finish is standard on all GS swivel and rigid rigs.
