Technical Specifications






Description
Floor Truck Lock To be used with casters having an overall height of 5 5/8″. Designed to keep equipment steady on level floors, floor truck locks use a rubber pad to create friction when activated by foot. They’re mounted between swivel casters and help hold carts, trucks, or mobile stations in place—without lifting the load. These locks are a dependable choice in settings like warehouses, labs, hospitals, food prep areas, and production lines. Standard steel models suit dry environments, while 304 stainless steel options are ideal for washdowns and corrosive conditions. Available for caster heights from 4” to 8”, they’re easy to install and work well on smooth surfaces such as tile or concrete.
FAQ
What are Floor Truck Locks
Floor truck locks are devices used to hold equipment in place on level floors by engaging a rubber pad with the floor for friction when you step on the activation pedal. They’re not designed to lift the equipment—install them between swivel casters for stability. Release by stepping on the release pedals. Available in standard and 304 stainless steel for wet or corrosive environments.
What environments and applications work best for Floor Truck Locks
Floor truck locks are perfect for warehouses, hospitals, food service, labs, and manufacturing where carts or equipment need to stay put on level floors during loading or work. They’re great for preventing unwanted movement on smooth surfaces like concrete or tile. Stainless steel versions suit washdown areas or corrosive settings like food processing plants or marine facilities.
What is the purpose of Floor Truck Locks
Floor truck locks provide friction to keep carts or equipment stationary on level floors without brakes on every caster. Step on the pedal to lower the rubber pad; it creates grip but doesn’t lift the load. Ideal for stabilizing platform trucks or mobile workstations during use.
How do Floor Truck Locks work
Step on the activation pedal to lower a rubber pad onto the floor, creating friction to hold the equipment. To release, step on one of the release pedals to retract the pad. They’re mounted between swivel casters and work on level floors only—not for inclines or lifting.
What sizes are available for Floor Truck Locks
Floor truck locks are sized based on caster overall height: for 4″ casters (retracted 4-5/8″, extended 5-7/8″), 5″ casters (retracted 5-5/8″, extended 6-7/8″), 6″ casters (retracted 6-5/8″, extended 7-7/8″), and 8″ casters (retracted 8-5/8″, extended 9-7/8″). Stainless steel options available in the same sizes.
What materials are used in Floor Truck Locks
Standard floor truck locks use stamped steel with a rubber pad for friction. Stainless steel versions are made from 304 stainless steel for corrosion resistance in wet or washdown environments, with the same durable rubber pad.
What are the main benefits of Floor Truck Locks
Floor truck locks offer reliable holding on level floors without needing brakes on all casters, easy pedal activation and release, and no lifting of the load. Stainless steel models resist rust and chemicals, making them durable for food service, hospitals, or labs, with quiet operation and floor protection.
How do I install Floor Truck Locks
Install floor truck locks between swivel casters on the cart frame using the 4″ x 4-1/2″ mounting plate (bolt hole spacing 2-5/8″ x 3-5/8″ to 3″ x 3″). Ensure the retracted height matches your caster’s overall height. Use at least 4 bolts (not included); don’t drill holes until you receive the locks. Position for easy pedal access on level floors only.
What maintenance do Floor Truck Locks require
Clean the rubber pad and mechanism regularly to remove debris, especially in dirty or wet environments. Check for wear on the pad and replace if needed to maintain friction. For stainless steel models, wipe down to prevent buildup. Avoid harsh chemicals or overloading, as they’re for holding, not lifting.
Where can I buy Floor Truck Locks
Get floor truck locks from Caster City’s website at www.castercity.com or call 800-501-3808 for assistance. Lead time is typically 2 days for fast delivery, with options in standard or 304 stainless steel.
What’s the difference between standard and stainless steel Floor Truck Locks
Standard floor truck locks use stamped steel for general indoor use on level floors. Stainless steel versions, made from 304 stainless, resist rust and chemicals, making them ideal for washdowns, food processing, hospitals, or corrosive areas while offering the same holding performance and sizes.
Are Floor Truck Locks suitable for inclined surfaces
No, floor truck locks are designed for level floors only and rely on friction from the rubber pad—they’re not brakes and won’t hold on inclines. For sloped surfaces, use casters with built-in brakes or consult for alternative solutions.

Can Floor Truck Locks be used with any caster
Floor truck locks should be matched to your caster’s overall height for proper retraction and extension. Install between swivel casters on the cart frame. They’re compatible with most plate-mounted casters, but ensure the rubber pad contacts the floor without lifting the load. For stainless steel casters in wet areas, choose the 304 stainless lock.
What industries commonly use Floor Truck Locks
Floor truck locks are popular in warehouses for platform trucks, hospitals for medical carts, food service for kitchen trolleys, labs for equipment stands, and manufacturing for workstation stability. Stainless steel models are favored in corrosive or washdown areas like pharma plants or marine facilities.
How do Floor Truck Locks compare to caster brakes
Floor truck locks provide friction-based holding on level floors without needing individual caster brakes, saving cost and simplifying setups. They’re not for inclines or lifting, unlike some total-lock brakes. Use them to supplement casters for added stability on carts or trucks.
Are Floor Truck Locks good for heavy loads
Floor truck locks hold equipment via friction but don’t bear load—they’re for stabilizing on level floors. Pair with casters rated for your total weight (e.g., up to 1,200 lbs sets). Avoid overload or abuse; for heavy-duty needs, ensure robust cart design.
What installation tips are there for Floor Truck Locks
Mount on the cart frame between swivel casters at a height matching your caster size for proper pad contact. Use 3/8″ mounting bolts (not included) on the 4″ x 4-1/2″ plate. Test on level floors to ensure the pad engages without lifting wheels. For stainless models, use in wet areas but avoid harsh chemicals on the rubber pad.
Can Floor Truck Locks be used in washdown areas
Yes, the 304 stainless steel versions are excellent for washdown areas like food processing or hospitals, resisting corrosion while the rubber pad provides reliable friction. Standard steel models suit dry indoor use; clean regularly to maintain performance.
