All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

This caster is not just a purchase; it’s an investment in improved operational efficiency and long-term durability.
This Colson D4.05109.921 SS 5" x 2" Polyurethane Stainless Caster – CasterHQ is rated to 750 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 Polyurethane wheel with a 2" 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 4" x 4-1/2" plate and a 3" x 3" 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 caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -40°F to 600°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 Polyurethane 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 6.5". 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).
