Truck Wheel Chocks In Rubber Cast Iron and Steel
A wheel chock is the cheapest thing on a loading dock and the one that most often is not there. S&L lists six models, SL-WC-01 to SL-WC-06, across folded steel, cast iron, laminated rubber and moulded rubber, so a site can match the chock to its yard surface rather than take whatever arrives.
Product Overview
What This Product Is and Where It Fits
Chock choice comes down to the yard surface and the handling. On a clean concrete apron a moulded rubber chock grips well and is quiet to place. On a gravel or broken surface a steel or cast iron chock bites in where rubber would skid.
Handling matters more than buyers expect. A chock that has to be carried the length of a trailer in the rain gets left in the cab. The models with a bail handle or a side carry handle are the ones that actually end up under a wheel.
SL-WC-02 carries Safety First Check Your Wheels cast into the face, which makes the chock legible as a safety item rather than a lump of iron someone might move.
All six models are listed in the same S&L range, so a site can standardise on one supplier while still running different chocks in the yard and at the dock face.
Key Benefits
Three Reasons Buyers Specify This Line
Six models rather than one compromise
Folded steel, cast iron, laminated rubber, curved steel, moulded rubber and diamond tread steel cover clean concrete through to broken yard surfaces.
Handles on the models that get carried
The laminated rubber chock has a welded steel bail handle and the diamond tread steel chock a side carry handle.
A cast safety message that cannot wear off
SL-WC-02 has its warning cast into the body rather than printed on it.
Application Scenarios
- Dock face restraint during loading and unloading
- Drop trailers parked in a yard
- Vehicle maintenance bays
- Rail and plant sidings where a vehicle is worked on
Who It Is For

Problems It Solves
- Trailer creep while a fork truck is inside the trailer
- Chocks that skid on a wet or broken surface

Materials
Materials and Finish
Folded and fabricated steel, cast iron, laminated rubber and moulded rubber depending on model. Steel models are finished in safety yellow.
ManufacturingHow It Is Made
Steel models are cut, formed and welded before painting. Cast models are poured and dressed. Rubber models are moulded or laminated and fitted with a handle where the model calls for one.
Quality Control
What Is Checked Before Packing
Profile and face condition checked on every model; handle weld checked on SL-WC-03 and SL-WC-06; paint coverage checked on the steel models.
CertificationsCertification Status
No third-party certification is published for Wheel Chocks in S&L's own documentation, so this page marks it TBC at quotation rather than implying one. For chocks the useful evidence is a rated vehicle weight rather than a mark. That rating is not published for these models, so ask for it in writing before you standardise on one.
Customisation
Options Within The Published Range
- Model selected for the yard surface and handling
- Safety yellow finish on the steel models
- Handle fitted where the model offers it
Comparison
How It Compares With The Alternatives
| Option | When To Choose It |
|---|---|
| Rubber chock | Grips clean concrete, quiet to place, no spark risk. |
| Cast iron chock | Bites into a broken or gravel surface and carries a cast-in safety message. |
| Steel chock | Hardest wearing of the three, and the diamond tread model has a side handle for carrying. |
Use Guide
Getting It Right On Site
- Place chocks at the rear wheels on the downhill side before the dock door is opened
- Push the chock firmly against the tyre rather than resting it near the wheel
- Use two chocks where the yard is graded or the trailer is being loaded from one end
- Replace a rubber chock once the gripping face has worn smooth

SL-WC-03 has a welded steel bail handle and SL-WC-06 has a side carry handle.
What is cast into the face of SL-WC-02?
Safety First Check Your Wheels, cast into the body so it cannot wear off.
