This spigot is square on both sides to prevent roll when using overhead or on boom stands.
Fits all Strobepro and almost all other stands with removable spigots.
Use the 1/4" to mount standard accessories like speedlites or the 3/8" for larger diameter accessories.
They are good and keeps the strobe from twisting
Genius idea! These are a must have if you boom lights, great to have in the grip bag. I am using these on Manfrotto 024 booms and it stops any spinning of large modifiers..great.
Solid, great quality!
works as expected
An essential piece of gear made better with the flat side to keep it from turning.
