Whether you're handling heavy loads in demanding environments or requiring smooth and reliable movement, this caster meets the highest standards of quality, safety, and efficiency.

Its phenolic wheels are designed to withstand heavy-duty workloads, providing a long-lasting solution for applications requiring robust performance. With a load capacity of 800 lb, it can handle demanding tasks while maintaining smooth movement under pressure. The phenolic wheel material ensures stability, wear resistance, and minimal friction.

This makes it suitable for industries that require high-performance equipment, such as food processing, pharmaceuticals, and chemical handling. The caster's compliance with RoHS and NSF standards (less thread guards) ensures its suitability for regulated environments, providing peace of mind for businesses that must meet stringent regulatory requirements.

This Colson D4.04109.331 BRK4 SS 4"x2" Phenolic Stainless Total Lock Caster is rated to 800 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 Phenolic wheel with a 2" tread width. Phenolic carries high loads on smooth, hard floors and tolerates heat, but transmits more shock than an elastomer tread.
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 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 -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 Phenolic wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 5.63". 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).
