These are built to the usual Global Trus quality, suitable for 50mm truss, rated at 250kg.
If you're connecting two of these together, for example to hang a dropped pole under some F34 truss, then you will also need a Conical as these are not supplied. The Bullet Pin and R Clip are however.
I'll be ordering more of these as my rig expands... just keep in mind the maximum loads... including the clamps which are weighty themselves
