Web lashing assembly

A web lashing assembly (commonly referred to as a tie-down strap, ratchet strap, or lashing strap) is a device used to secure cargo or equipment on road vehicles. Such assemblies are made from man-made fibre webbing and include end fittings that allow the assembly to attach to anchor points, loop over cargo, or connect directly to the cargo. They typically incorporate a tensioning mechanism, such as a ratchet, to apply pre-tension and maintain the load securely during transport. EN 12195-2 specifies the strength, construction, marking, and testing requirements for these assemblies to ensure safe load restraint.

In the US, regulations establish requirements for the identification, condition, and safe use of tie-down devices, and requires that tie-down assemblies, including synthetic web tie-downs such as ratchet straps, have a manufacturer-assigned working load limit (WLL) that is permanently marked or otherwise identifiable.

Webbing with a linking device is used for the fastening of goods with trucks, trailers, pallets, boxes, and containers. This is also known as ratchet lashing, ratchet straps, ratchet tie downs, tie down straps and lashing with webbing.

Custom ratchet straps can have hooks such as J hooks, D hooks, E track fittings, and with S hooks being the most popular industry-standard.
