A ratchet lock or, in a popular way, a “ratchet” is the main element of the tie-down strap. The ratchet is used to tension the belt and keep it taut. The overall reliability of the tie-down strap largely depends on the quality of the ratchet mechanism.
The main advantages of this ratchet are its compact size and the presence of an ergonomic rubber handle, thanks to which the ratchet can be operated without gloves even at sub-zero temperatures.
