The Impact Swivel Umbrella Adapter is a sturdy, well thought out piece of grip equipment that allows you mount a light and umbrella on stands up to 5/8" diameter. The tilt handle is a ratcheting type that allows you to reposition it as you tighten it down- a very handy feature in restricted spaces.
Two reversible 5/8" threaded studs are included. One is a female 1/4"-20 to female 3/8" that can be used as a stand adapter and the other is a male 1/4"-20 to male 3/8"-16 that can be screwed into a flash with a female tap. The studs are tightened down with a large sliding T-handle while the swivel tightens onto the stand with a large knob. The Swivel Adaptor's umbrella receptacle will accept 7mm and 8mm umbrella shafts.
