Pro-source PSRL-5/16-3/8 Loadbinder 5400 Lb Type B

Product Description

The PRO-SOURCE PSRL-5/16-3/8 is a Type B ratchet loadbinder rated to 5,400 pounds load limit, designed for securing cargo with chain during transport and rigging operations. It provides 8 inches of take-up travel, allowing the operator to tension the chain to a secure working load. This loadbinder is compatible with 3/8 inch Grade 43 chain and 5/16 inch Grade 70 chain, covering two of the most common chain grades used in freight and flatbed tie-down applications. At 12 pounds, it is built for repeated field use by transportation and rigging professionals.

This loadbinder is suited for flatbed trucking, construction site rigging, and general cargo securement where DOT-compliant chain tie-down assemblies are required. It is a standard tool on flatbed trailers securing heavy equipment, lumber, steel, and other freight that must be restrained to Federal Motor Carrier Safety Administration (FMCSA) cargo securement standards. The Type B ratchet-style mechanism gives the operator positive mechanical advantage when tensioning the chain, making it appropriate for loads requiring consistent and verifiable tension.

Installation Notes

Loadbinders are installed by transportation and rigging professionals as part of a complete chain tie-down assembly. Always verify that chain grade and working load limit ratings match or exceed the loadbinder rating before assembly. Inspect hooks, chain links, and the ratchet mechanism for wear, cracks, or deformation before each use. Never exceed the stated load limit and never use impact tools to tension the ratchet mechanism.
