What does the Colson part number D4.06109.925-BRK4-SS mean?

Colson encodes its part numbers by series, wheel material, wheel diameter, plate size, bearing type, and mount style. The D4.06109.925-BRK4-SS is decoded by your CasterHQ engineer at order time — call us at 844-439-4335 for a full breakdown.

What is the load capacity of the D4.06109.925-BRK4-SS?

900 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.

Will the D4.06109.925-BRK4-SS work on rough concrete?

Yes for cast iron and steel wheels. 6" diameter rolls over expansion joints and seams cleanly. For polished or epoxy floors, ask us about poly-on-iron or thermoplastic options.

Is the D4.06109.925-BRK4-SS made in the USA?

Colson's industrial casters are USA-manufactured. We provide BAA/TAA-compliant Country-of-Origin documentation on request for federal procurement, typical turnaround under 24 hours.

What is the lead time?

In stock at CasterHQ Mansfield, TX. Quantities 1-100 ship same-day for orders placed before 2:00 PM Central. Larger quantities ship within 1-2 business days.

What is the load capacity of this caster?

This Colson D4.06109.925-BRK4-SS 6" x 2" Polyurethane Hi Caster — 900 lb is rated to 900 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.

What wheel does this caster use?

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.

What plate size and bolt pattern does it use?

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.

Is this a swivel or rigid caster, and how does the brake work?

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.

What temperature range can this caster handle?

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.).

What floors and applications is it best for?

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.

What is the overall mounted height?

The overall height (floor to top of plate or stem) is 7.5". Account for it when checking equipment clearance, dock height, and ergonomic working height.

How do I order, and what are the terms?

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).
