The 4" x 1.25" Stainless Thermo Side-Lock Caster stands out due to its combination of durability, performance, and versatility. Whether you're operating in extreme temperatures or simply need a high-quality caster for industrial use, this product offers the perfect balance of strength and smooth mobility. Its stainless steel construction ensures that it resists corrosion, while the crowned tread wheel profile promotes easy, efficient movement even under heavy loads. With a load capacity of 300 lb, this caster is ready to meet the demands of your toughest tasks.
This Colson 2.04456.52 HT BRK1 4" x 1.25" Thermo Stainless Side Lock Caster 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 uses a top-plate mount with a 2-1/2" x 3-5/8" plate and a 1-3/4" x 2-13/16" bolt pattern. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
This is a Swivel with Brake caster with a wheel brake. Swivel casters rotate 360 degrees for full maneuverability. The brake locks the wheel to hold the load in place. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
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 overall height (floor to top of plate or stem) is 5-1/8". 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).
