These separate ratchet parts are available with a band width of 25, 35, 50 or 75 mm.
The short part is composed of a ratchet locking mechanism as well as an optional hook. The ratchet mechanism can be associated with the long part of the tie-down strap (also called the tension band or the tension part).

The 25mm lashing straps are ideal for securing light loads, while the 75mm straps have been specially designed for securing extremely heavy loads.
