Colson 1 Series casters are one of the most durable 1″-wide single-wheel caster solutions on the market, handling working loads of up to 145 lbs. per caster. Utilizing thicker steel than most competitors and an attractive zinc finish, this series provides reliability and performance for any light duty cart, rack, or cabinet application (plus many others!). Full double ball hardened raceways offer increased performance and swivel action. Each caster is pre-lubricated with ‘Colson 45’ multi-temp grease, which works in both hot and cold environments. If you need more capacity or a wider wheel footprint for stability, step up to the Colson 2 Series for capacities of up to 325 lbs. per caster and 1-1/4″ wide wheel treads.
