A narrower version of our popular Colson 4 Series casters, this series provides an excellent solution for narrow flooring tracks or simply a smaller footprint, handling working loads of up to 800 lbs. per caster. Featuring a 1-1/2″-wide wheel tread, this series provides a reliable option for medium duty applications where a narrower footprint is desired (versus a 2â€ wide tread width). Zinc plating provides an attractive and durable finish to steel rig construction. Hollow axles with grease fittings along with grease zerk on swivel raceways allow for easy maintenance of each caster. Want the wider 2â€ tread width? See our popular 4 Series standard 2â€ wide series.
