The Albion 272CA04101S swivel caster features a 4" x 1.5" wide dual wheels and a 4-1/2" x 6-1/4" top plate, capable of a 1200 lb. capacity per caster. Complete caster specifications and downloadable CAD model are provided below. This series is designed for greater dynamic capacity and better distribution of floor load with the lowest possible overall height. These casters have differential action when changing direction, thus greatly reducing the scrubbing effect resulting from the use of wide-faced, small-diameter wheels.
