This Colson MTG53 3.5" x 1.25" Polyolefin Caster – 1-1/8" to 1-3/16" Stem is rated to 230 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.
This caster runs a Polyolefin wheel with a 1-1/4" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
This caster uses a top-plate mount. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
Rated for -20°F to 180°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Polyolefin wheel performs best on smooth to semi-smooth floors including sealed concrete, tile, and epoxy. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 4.56". Account for it when checking equipment clearance, dock height, and ergonomic working height.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
