Manfrotto 035 Super Clamp is a universal clamp for mounting to flat surfaces and tubes with diameters from 13 to 55 mm. It includes a 16 mm socket. Maximum load: 15 kg. Clamp weight: 0.41 kg. Its versatility comes from the ability to mount on many stands. For example, to place a second light slightly lower and to the side of the main one, you can attach a Super Clamp to a stand and mount the second light via an adapter or a spigot.
