Deck Clamp
Also known as
Doughty Clamp, Euro Clamp, Side-Entry Clamp, Swivel Coupler, Hook Clamp with Spigot
Used for
Clamping to the side of a pipe or truss chord to hang a fixture via a spigot (threaded stud) rather than a T-bolt. Common in European touring and theater rigs where the Doughty / Euro fitting is the standard — a fixture's spigot receiver slips over the clamp's M12 stud and is secured with a locking nut.
Trade note
"Doughty" is a UK brand name (Doughty Engineering) that became the generic British term for this style of side-entry pipe clamp, the same way "Crescent" did for adjustable wrenches. In North America the equivalent is often called a Euro clamp or swivel coupler. If you're on an international show, expect both Doughty-style and half-coupler hardware on the same rig.
