This Colson 2.04267.445 4" x 1.25" Performa Rigid Caster – 7/8" to 15/16" is rated to 300 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 Gray Rubber wheel with a 1-1/4" tread width. Rubber absorbs shock and protects floors, and runs quietly, which suits noise-sensitive and light-to-medium duty use.
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 Gray Rubber wheel performs best on rough, uneven, or outdoor surfaces such as asphalt, gravel, and cracked concrete. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 5.25". 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).
