DH Caster 4" Plate Mount Floor Lock, C-FL4

DH Casters Lock With 4 Inch Wheel Use

DH Casters lock with 4 inch wheel is a plate mount floor lock that holds a wheeled unit steady when the job calls for stability. Welded steel construction creates a solid body that resists flex in service, so the lock can handle repeated foot operation on busy shop floors. The non-slip rubber pad grips the floor surface when engaged, which limits unwanted rolling as loads are moved on and off carts or benches. The foot-operated design lets installers and operators engage or release the lock while keeping hands on the load, which supports safer and more controlled positioning. As a plate mounted caster component in builders hardware, this lock integrates into material handling setups where precise hold is needed during assembly, loading, or cutting work.

Key Floor Lock Details That Support Daily Work

• Welded steel construction builds a rigid lock body that resists bending in normal use, which supports consistent engagement stroke and predictable holding performance over many lock and release cycles.
• A non-slip rubber pad contacts the floor during operation, increasing friction at the contact point so carts or benches resist creeping when lateral forces or vibration act on the wheels.
• The foot-operated mechanism is designed for actuation by foot, allowing technicians to engage or disengage the lock while maintaining hand control of tools, materials, or cart handles around the work area.
• The plate mount design places the lock on a flat mounting plate, matching common plate mounted casters and allowing the lock to occupy a stable footprint under the equipment frame.

Plate Mount Floor Lock Fit And Bolt Layout

This floor lock uses a plate size of 3-15/16 inches by 4-1/2 inches, giving installers a defined mounting footprint that aligns with typical plate mounted caster layouts. Plate hole spacing ranges from 2-5/8 inches by 3-5/8 inches to 3 inches by 3 inches, providing a window of mounting positions so the plate can land on existing frame steel or new fabrication without redrilling beyond that pattern. The attaching bolt size is 3/8 inch, which sets the fastener diameter for the mounting holes and guides drill size and nut selection in the supporting structure. The SAP description states an overall height of 5-5/16 inches to 5-5/8 inches, giving a working height range that helps match the lock position to the loaded caster height on the same unit.

Using The C-FL4 Floor Lock In Shop And Site Setups

Where This DH Casters Floor Lock Is Applied

The C-FL4 floor lock from DH Casters sits in the builders hardware and plate mounted casters category, so it is suited to carts, mobile benches, and similar wheeled equipment built around plate mount caster sets. The welded steel construction matches the robust frames typically used in woodworking and fabrication environments, helping the lock act as a structural extension of the equipment base. With an overall height between 5-5/16 inches and 5-5/8 inches, the lock works in setups built around casters near that loaded height, bringing the rubber pad into contact with the floor when engaged. The 3-15/16 inch by 4-1/2 inch plate size and the 2-5/8 inch by 3-5/8 inch to 3 inch by 3 inch hole spacing window support mounting to steel tube, angle, or plate members that accept a 3/8 inch attaching bolt pattern.

Why These Floor Lock Details Matter In Use

Because the C-FL4 uses welded steel construction, the body resists twisting when the operator steps on the pedal, which keeps the travel of the non-slip rubber pad consistent from unit to unit. That consistent stroke helps maintain predictable contact pressure against the floor, so operators know how the cart or bench will behave during engagement. The non-slip rubber pad improves grip on typical shop floors, so line workers can load or unload materials without the unit drifting. Foot operation lets staff lock or unlock movement without changing hand position on the load or handles, streamlining repositioning during repeated tasks. The 3-15/16 inch by 4-1/2 inch plate and 3/8 inch attaching bolt size supply a defined interface that fabricators can design around when laying out mounting flanges or plates. The hole spacing range between 2-5/8 inch by 3-5/8 inch and 3 inch by 3 inch gives some flexibility in where holes land relative to frame members, which helps reduce layout conflicts during retrofits or new builds. The stated overall height range of 5-5/16 inch to 5-5/8 inch indicates the working envelope of the lock, allowing designers to plan caster selection and frame elevation so the pad contacts the floor at the correct point in the stroke.
