Factory Wholesale High-Quality Floor Lock for Lifting Height 151/180/210/255 mm 4/5/6/8-inch Style Floor Lock Brake

This industrial‑grade floor lock (also known as leveler stopper) is designed to stabilize mobile trolleys, work carts and workshop equipment. Available in 4‑inch, 5‑inch, 6‑inch and 8‑inch sizes. It replaces traditional caster braking to hold heavy‑duty equipment firmly off the ground. Once activated, it lifts the casters slightly away from the floor, eliminating wheel drifting and wobbling, delivering far more reliable positioning than standard caster brakes. Widely used for workshop trolleys, tool carts, assembly‑line equipment, warehouse transport carts and industrial workstations.

1. Heavy‑Duty Steel Structure Main body adopts thick stamped steel with green powder‑coated top mounting plate. The surface resists scratches, oxidation and rust for long‑term workshop use. All connecting arms and linkage parts are high‑strength galvanized steel, resisting deformation under heavy load.
2. Height‑Adjustable Screw Stem Precision threaded lifting stem supports flexible height adjustment. Users can fine‑tune the lifting height to lift casters completely off the ground, adapting to uneven floors and different caster wheel diameters. It compensates ground height differences and keeps equipment level.
3. Solid Base Foot Pad Large‑diameter metal base pad with anti‑slip bottom surface. Provides large contact area with the floor to bear heavy static load. It prevents slipping and avoids scratching concrete, epoxy and tile floors.
4. Foot‑Operated Linkage Mechanism Robust foot‑pedal linkage design. Operate by foot, no hand tools required. Step down to engage the floor lock and raise the cart; step the release lever to retract the foot pad so casters can roll freely. The mechanical linkage is durable for repeated frequent operation.
5. Standard Top Mounting Plate Pre‑punched flat mounting plate for bolt‑on installation. Matches common industrial caster mounting hole patterns. Easy to mount onto cart frames, equipment bases; simple to replace or retrofit existing trolleys.
