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.

The 5" x 2" Stainless Polyolefin Precision Ball Bearing Side-Lock Caster with 4" x 4.5" Plate (model D4.05109.835 BRK7 SS) is engineered for superior performance in a wide range of industrial and commercial applications. This caster is designed with durability, smooth performance, and easy maneuverability in mind, ensuring a long-lasting solution for all your material handling needs. Whether you are moving heavy equipment, machinery, or tools, this caster provides optimal performance in various settings, from manufacturing floors to food processing facilities.
Made with high-quality stainless steel and a polyolefin wheel, this caster is built to withstand demanding conditions while maintaining its strength and reliability. The stainless steel construction offers excellent corrosion resistance, making it ideal for environments where exposure to moisture, chemicals, or harsh conditions is a concern. The polyolefin wheel, known for its durability, provides a smooth surface for effortless movement, reducing friction and increasing efficiency in high-traffic areas.
Equipped with pedestal precision ball bearings, this caster ensures smooth and efficient movement even when bearing heavy loads. The precision design minimizes friction, allowing for easier handling of equipment and reducing wear and tear over time. This is particularly important in settings where continuous movement is necessary, such as assembly lines or warehouses, where downtime can be costly.
The side-lock brake (DTBRK7) allows for secure locking of the caster, preventing unintended movement when the caster is not in use. This provides added stability and safety, particularly in environments where safety is critical, such as hospitals, labs, and factories. The top lock brake is easy to engage and disengage, providing an efficient way to ensure the caster stays securely in place when needed.
Operating efficiently within a temperature range of -45°F to +180°F, this caster is ideal for use in both cold and hot environments. Whether it’s an industrial freezer or a high-temperature machine shop, this caster will continue to function effectively without compromising its integrity. This broad temperature tolerance makes it suitable for a wide range of industries, including food processing, pharmaceutical production, and heavy manufacturing.
The caster comes with a 4" x 4-1/2" top plate, making installation a straightforward process for a variety of equipment setups. The bolt hole pattern (ranging from 2-5/8" to 3" x 3" to 3-5/8") ensures compatibility with many existing mounts, offering versatility in different industrial and commercial applications. This caster is a flexible choice for businesses looking to upgrade their equipment or replace existing casters with minimal hassle.
Not only does this caster deliver superior performance, but it also meets industry standards for safety and environmental compliance. The product is RoHS compliant and NSF certified (excluding thread guards), making it a suitable option for use in commercial kitchens and other food-grade environments. This adherence to high standards ensures that the caster can be trusted for both performance and safety, providing peace of mind for your business.
We stand behind the quality of the 5" x 2" Stainless Polyolefin Precision Ball Bearing Side-Lock Caster with a 3-year warranty. This warranty guarantees that the caster will perform as expected under normal usage conditions. Should any issues arise, our dedicated customer support team is always ready to assist, ensuring you get the best possible experience with our products.
In summary, the D4.05109.835 BRK7 SS caster offers a perfect balance of strength, safety, and versatility. Designed for heavy-duty industrial and commercial applications, it delivers smooth movement, secure locking, and long-lasting durability in harsh conditions. Its stainless steel construction, precision bearings, and FDA-approved grease make it a top choice for businesses seeking reliability and efficiency in their material handling equipment.
This Colson D4.05109.835 BRK7 SS 5" x 2" Polyolefin Side Lock Caster is rated to 650 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 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 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 6-1/2". 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).
