The Colson 2.04456.544-BRK1 is a 4" x 1.25" polyolefin plate-mount caster rated 275 lb per caster, mounted on a 2.5" x 3.625" Top Plate plate. It is built for industrial use where part-number-exact specification, capacity, and bearing life take priority. The 4" diameter rolls cleanly over expansion joints and floor seams smaller wheels stall on. In stock at CasterHQ Mansfield, TX with same-day shipping on quantities of 1-100 placed before 2:00 PM Central. BAA / TAA documentation available on request for federal, defense, and aerospace procurement.
I spec Colson on standard-duty industrial carts where bearing life and quiet roll matter more than maximum capacity. The 2.04456.544-BRK1 earns its place when smooth-roll quiet operation and floor protection are the controlling spec. Pair 4" on the steered axle with a matching rigid version on the trailing axle for true four-position cart kinematics. If your floor has expansion joints over 1/2" wide, step up to a larger wheel diameter.
Colson encodes its part numbers by series, wheel material, wheel diameter, plate size, bearing type, and mount style. The 2.04456.544-BRK1 is decoded by your CasterHQ engineer at order time — call us at 877-721-7837 for a full breakdown.
275 lb per caster dynamic. On a 4-caster cart with even load distribution and a 1.3x safety factor for moving loads, that yields the rated working capacity per cart.
Yes for cast iron and steel wheels. 4" diameter rolls over expansion joints and seams cleanly. For polished or epoxy floors, ask us about poly-on-iron or thermoplastic options.

Constructed from durable stainless steel and featuring a corrosion-resistant polyolefin wheel, this caster ensures reliable performance under heavy loads and in harsh environments. With a maximum load capacity of 275 lbs, it is ideal for applications that require both strength and ease of movement. The Delrin Bearing provides smooth, low-maintenance operation, while the side-lock brake offers secure positioning when needed.
This caster is designed with a full double ball hardened raceway, providing enhanced durability and load support. The raceway features multi-temperature grease, allowing for smooth operation in both extreme heat and cold. The Delrin Bearing contributes to long-term wear resistance, ensuring minimal maintenance and reliable performance over time. The flat tread polyolefin wheel is crafted to withstand heavy use and reduce rolling resistance, making it an optimal choice for demanding applications.
Equipped with a top lock brake (BRK1), this caster provides reliable stability for stationary positioning. The side-lock mechanism is easy to engage, giving operators control and peace of mind in various settings. The 2.5" x 3.625" fastening plate allows for secure and flexible mounting options, accommodating a variety of bolt patterns and installation requirements. With a mounting height of 5.13 inches, it is well-suited for installations where stability and space are crucial.
Whether used in manufacturing facilities, warehouses, or retail environments, the 4" x 1.25" Stainless Polyolefin Side-Lock Caster is a dependable choice for heavy-duty applications. Its corrosion-resistant design makes it suitable for humid or chemically exposed environments, while the 3/8" 304-grade stainless steel axle provides a robust structure that withstands wear and tear. The caster’s compliance with RoHS and NSF standards (excluding thread guards) underscores its quality and versatility in various settings.
Our 4" x 1.25" Stainless Polyolefin Delrin Bearing Side-Lock Caster is backed by a 3-year warranty, ensuring quality and performance you can count on. Each caster undergoes stringent testing to meet high industry standards, delivering a product that combines durability, safety, and ease of use. With a commitment to customer satisfaction, we are here to provide support and assurance for any industrial or commercial needs.
This Colson 2.04456.544-BRK1 4" x 1.25" Polyolefin Caster — 275 lb is rated to 275 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 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 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 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).
