Quantity discounts are available on this product
All of our extruded aluminium couplers have been designed to accommodate two tube sizes. By utilising their unique tube receiving feature. Each inner face has two arcs so that the coupler is capable of clamping onto 50.8mm (2") and 48.44mm (1 29/32") OD Tubing.
Originally designed for use with scaffold towers in the construction industry, these couplers quickly found a use for rigging in the creative industries.
SAFE WORKING LOAD – 500Kgs (tensile load with safety factor of 8)
Extracts from Test Report:
“The right angle couplers and the swivel couplers met the specification of the relevant sector of BS 1139:1991, provided they were secured with nuts torque tightened to 55Nm. This torque or more can be achieved with a standard' scaffolding wrench. It should be noted that a specially modified torque wrench adapter is required if wing nuts are used."
Note: Refer to manufacturers/suppliers specification or advice when coupling onto aluminium towers, especially ones with thin wall tubing.
The main considerations are:-
- Over tightening when couplers are fitted with nuts
- Tightening and crushing thin wall tubing
- Poor slip resistance when couplers are fitted with wing nuts - in these cases ensure couplers have a check fitting to prevent slipping or are located above a check point e.g. a tee piece joint; using the appropriate couplers for the applications and using extra couplers if necessary; if in doubt contact your manufacturer/supplier.
The couplers are supplied with wing nuts as standard, or hexagonal nuts if specified.
The couplers can be stamped with “SWL 500Kgs” if specified.
