The Albion Casters 4" x 2" Industrial Line USA Rig Side Locking Caster is engineered for exceptional performance and durability in industrial applications. With a wheel diameter of 4 inches and a width of 2 inches, this caster is designed to support heavy loads while maintaining ease of movement. The reinforced polypropylene wheel offers superior resistance to impact and wear, making it suitable for demanding environments where reliability is crucial.
The side locking mechanism is a standout feature, providing enhanced stability when stationary.

The caster’s robust construction is ideal for use in warehouses, factories, and other high-traffic areas where durability and strength are paramount.
Designed with precision and quality in mind, this caster meets the rigorous standards of industrial applications. Its compatibility with various mounting systems and ease of installation make it a versatile choice for upgrading or replacing casters on equipment and machinery. The Albion Casters 4" x 2" is not only a practical solution for mobility but also a testament to engineering excellence, promising long-term performance and reliability.
This Albion 16RT04201SFBA 4" x 2" Polypropylene Caster with Wheel Lock Brake 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 Polypropylene 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 2-5/8" x 3-5/8" slotted to 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.
Rated for -20°F to 250°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 Polypropylene 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 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).
