These useful clamps can be put to multiple uses round the studio, they fit to most standard light stands and can be used to hold boom arms in place.
The double clamp allows you to attach a boom arm or any other type of lighting accesory to the frame of your light stand instead of the top stud/spigot, this means you are still able to use the top stud/spigot of your light stand to attach any other lights or accesories you want.
Clamp has 4 different diameter holes for locking different sized boom arms and stands. The clamp can be fully rotated to any angle you require.
Hole diameters are 31, 24, 20, 17mm (please note that these the tightening method of the lock nut will compensate for a few mm with stands bigger in diameter to the hole sizes stated).
