The 6" x 2" Stainless Polyolefin Delrin Bearing Caster with Total Lock and 4" x 4.5" Plate (D4.06109.831 BRK4 SS) is built to handle the demands of heavy-duty industrial and commercial applications. With a load capacity of 700 lbs, this caster is designed for optimal performance, offering secure movement and durability even in the most challenging environments. Whether you're navigating smooth or rough surfaces, this caster will provide a reliable solution for your mobility needs.
Constructed with a robust stainless steel finish, this caster ensures excellent resistance to corrosion, making it an ideal choice for environments with exposure to moisture, chemicals, or extreme temperatures. The Polyolefin wheel provides superior strength, minimal wear, and smooth operation, while the Delrin bearing ensures reliable, quiet performance over time. The total lock brake provides safety by securely locking both the wheel and swivel, offering stability and control when stationary.
The caster is lubricated with -40°F to 600°F performance grease that is FDA-approved, making it safe for use in food-grade environments. This is particularly important for industries where sanitation and safe, consistent performance are top priorities. The grease ensures smooth movement even in extreme temperature ranges, from -45°F to +180°F, making the caster suitable for diverse applications.
The 4" x 4-1/2" top plate with a versatile bolt hole pattern (ranging from 2-5/8" to 3" x 3" to 3-5/8") allows for easy installation on a wide variety of equipment. With the recommended 3/8" plate bolt size, it ensures a secure connection and enhances the caster's overall stability. The caster's swivel radius of 6.75 inches allows for easy maneuverability, while the lack of a swivel lock gives you unrestricted movement when needed.
Our commitment to quality and customer satisfaction is paramount. Each caster undergoes rigorous testing to ensure it can withstand demanding use and provide reliable service in a wide range of industrial and commercial settings. We offer dependable customer support to address any inquiries or concerns, ensuring that you receive the highest level of service with every purchase.

Designed for long-lasting service, this caster enhances the efficiency and mobility of your operations, even in the most demanding environments.
This Colson D4.06109.831 BRK4 SS 6" x 2" Polyolefin Total Lock Stainless Caster is rated to 700 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 Polyolefin 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 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 Polyolefin 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 7.5". 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).
