Size and contact are the starting checks
The documented pair contains two rubber chocks, each 8 × 4 × 6 inches. Compare their shape with the tyre and the intended ground contact, rather than assuming any wedge fits every vehicle. The textured surfaces and moulded handle are handling and contact features, not an independently verified universal holding rating.
Chocks address rolling, not vehicle support
A chock helps restrain wheel movement in a suitable setup. It does not carry the elevated vehicle at its support points, and adding chocks does not make it acceptable to work beneath a hydraulic jack alone. Plan lifting, support and restraint as separate functions. The ESCO pair and Arcan or SUNEX jack cover different stages with their own instructions.
Ground conditions remain decisive
Follow the chock and lifting-equipment requirements for surface and placement. A soft or sloping area cannot be declared suitable simply because rubber chocks are present. Check for contamination and damage that could affect contact. Use the vehicle procedure to identify the wheels and directions that need restraint; this product review does not provide a universal placement instruction for every job.
A small purchase with a defined place in the kit
The carrying handles make the pair easier to retrieve and store, which matters if equipment otherwise remains unused in a corner. Keep the pair available with the lifting equipment and inspect it before work. Confirm the exact 70472 two-pack when ordering; a generic chock photo is not enough to establish quantity, dimensions or compatibility.
