Extracts from Test Report:

“The right angle couplers and the swivel couplers met the, specification of the relevant , section 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 adopter is required if 'wing nuts are used Info., 55Nm = 40.3 lbf.ft"

SAFE WORKING LOAD – 500Kgs (tensile load with safety factor of 8)

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 - over 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.

We can supply any of our types of Coupler with either wing nuts or hex nuts and stamped with stamped with “SWL 500Kgs” if specified.
