The Durastar 5-3/4" Floor Lock is expertly engineered to stabilize carts, mobile workstations, and equipment in industrial and commercial environments. Designed with a heavy-duty steel frame and a widely compatible 4" x 4-1/2" (03 top plate), this floor lock offers a dependable solution for securing mobile units during stationary tasks.
Its extended height of 5-3/4" ensures solid floor contact for optimal stability when engaged, while the retracted height of 5-1/16" allows for unobstructed mobility.

Engineered to meet industry standards, the bolt hole pattern (2-5/8" x 3-5/8" to 3" x 3") and 3/8" attaching bolt diameter offer flexible installation across a variety of base configurations. Whether you are outfitting new carts or upgrading existing setups, this floor lock is a reliable, maintenance-friendly addition to your mobility solution.
Backed by Durastar’s commitment to quality and durability, this floor lock not only enhances workplace safety but also improves workflow efficiency by ensuring equipment stays exactly where you need it—when you need it. Trust Durastar to deliver performance-driven design with precision engineering you can rely on.
This caster uses a top-plate mount with a 4" x 4-1/2" plate and a 2-5/8" x 3-5/8" 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 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.).
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).
