Colson 3 Series are an ideal industrial solution for when a larger footprint and greater weight capacity are needed over conventional 1-1/4″-wide casters, handling working loads of up to 400 lbs. per caster. Zinc plating provides an attractive, yet durable finish against common corrosion causes. Full double ball hardened raceways offer increased performance and swivel mobility. Each caster is pre-lubricated with ‘Colson 45’ multi-temp grease, which works in both hot and cold environments. 3 Series casters feature a hollow axle with grease holes in wheel bearing for greater maintenance convenience.
