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.
