Scaffolding Couplers

Scaffolding Couplers are the fittings which hold the tubes together. There are three basic types: scaffolding right-angle couplers, scaffolding putlog couplers and scaffolding swivel couplers. To join tubes end-to-end scaffolding joint pins (also called spigots) or sleeve couplers are used, or both together. Only right angle couplers and swivel couplers can be used to fix tube in a ‘load bearing connection’. Single couplers are not load bearing couplers and have no design capacity.

Other common materials include base plates, ladders, ropes, anchor ties, reveal ties, gin wheels, sheeting, etc.

 Despite the metric measurements given many scaffolders measure tubes and boards in imperial units. With tubes from 21 feet down and boards from 13 ft down.
