One tube standard.
Every coupler in the range fits 48 to 51mm scaffold, truss and fly-bar tube, so one fitting standard works across your rig. Start with the family that matches the job, then spec the working load.

The fitting that
holds the rig.
A coupler is the fitting that connects gear to a tube. All four types fit 48 to 51 mm scaffold, truss and fly-bar tube and are supplied load-rated and stamped with a working load limit. Part of the full Lifting & Rigging range.
- Half coupler. Clamps one tube for a fixed point: lights, speakers, pipe-and-drape.
- Swivel. Joins two tubes at any angle.
- Self-lock. Grips under load, fast to rig and de-rig.
- Quick. Hook on, tighten, move on.

Pick the coupler,
not the compromise.
Four coupler families on one tube standard. Pick by the job.
One jaw. One fixed connection.
A single forged jaw on one tube: the fixed-point fixing for lights, speakers and pipe-and-drape.
Two tubes, any angle.
Two jaws on a central pin join two tubes and rotate a full 360 degrees, for bracing, cross beams and non-standard structures.
Hooks on. Grips under load.
Hooks onto the bar and grips automatically as soon as the load applies; you set final tension with the T-handle. Fast and secure for quick installs and de-rigs.
Hook, tighten, go.
Hook it on, tighten, move on: the time-saver for hanging fixtures without threading a bolt every time.
