Cable-Tie Ratchet Strap

The serrated tail/strap end of a self-locking (ratchet) cable tie, which is threaded through the tie's own locking head, where a pawl engages the strap teeth so it can tighten but not back out.

How it connects

Tail is pushed through the head's strap channel; a flexible pawl rides over the serrations and catches against them, giving a one-way ratchet lock. No sealing. Standard ties are permanent; release-type ties have a lever to lift the pawl.

Male and female halves

Tail/strap is the male (inserted) half; the head with strap channel and pawl is the female (receiving) half. This port is the male tail.

Common sizes

  • Strap widths roughly 2.5-9 mm (e.g. 2.5, 3.6, 4.8, 7.6, 9 mm), lengths about 100-1000 mm; mates only with heads of the same tie width/series.

  • mount-head and push-mount ties
  • stainless steel ball-lock ties
  • inside-serrated vs outside-serrated straps

Good to know

The male tail and female head are normally on the same cable tie. Widths are nominal and vary by maker, so cross-brand mating is not guaranteed. IEC 62275/UL 62275 address electrical cable-tie performance rather than mating dimensions; product applicability must be checked.
