The Colson 2.03456.52-HT-BRK4 is a 3.5" x 1.25" thermo plastic plate-mount caster rated 300 lbs, ideal for light to medium per caster, mounted on a 2.5" x 3.625" top plate for secure attachment plate. It is built for industrial use where part-number-exact specification, capacity, and bearing life take priority. The 3.5" 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 2.03456.52-HT-BRK4 earns its place when smooth-roll quiet operation and floor protection are the controlling spec. Pair 3.5" 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 2.03456.52-HT-BRK4 is decoded by your CasterHQ engineer at order time — call us at 844-439-4335 for a full breakdown.

This Colson 2.03456.52-HT-BRK4 3.5" x 1.25" Thermo Plastic Caster — 300 lb 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 Total Lock 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 4.69". 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).
