How it connects
Opposing curved foot hooks slip into the strut channel slot and engage under the inward lips; tightening the central clamp bolt draws the hooks up tight against the channel lips while securing the seated pipe.
Male and female halves
Male hooks mating with the female channel lip slot.
Usually connects to
- standard strut channel open slot / lips (1-5/8 in channel)
Common sizes
- Fits standard 1-5/8 in (41 mm) strut channels; accommodates conduit/pipe trade sizes from 1/2 in up to 4 in
Where it is used
electrical installationsplumbing and mechanical pipingHVAC duct and pipe support
Variations
- one-piece saddle clamp (e.g. Cobra style)
- two-piece interlocking hooked strut pipe strap
How to recognise it
Recognized by stamped metal legs extending downward from a pipe saddle, terminating in outward/upward curled hooked tabs sized to catch beneath the rolled lips of a 1-5/8 inch strut channel slot.
Often confused with
| Confused with | How to tell them apart |
|---|---|
| Strut channel nut (spring nut) | A channel nut inserts into the channel with grooves that bite into the lips when turned and receives an independent threaded bolt, whereas hooked clamp feet are integral to the pipe clamp saddle itself. |
| Two-piece bolt-together strut pipe strap | Traditional two-piece strut straps hook independently into the channel lips and clamp together with a separate cross bolt and nut through top tabs. |
