The TG20:13 Operational Guide has now been withdrawn from sale as we enter the transition period to TG20:21. The TG20:21 Operational Guide is available electronically via the NASC ePortal TG20:21 subscription. Printed copies will be available later in 2021, to holders of NASC ePortal TG20:21 subscriptions. The TG20 Operational Guide contains detailed practical guidance for most common types of scaffolding, supported by structural research and calculation. Guidance is provided for a range of standard structures which includes independent scaffolding, interior birdcages, chimney stack scaffolds, loading bays, ladder-access towers, free-standing towers, lift shaft towers, putlog scaffolding, exterior birdcages, tube and fitting mobile towers, tube and fitting loading bays without beams, and tied independent scaffolds with three inside boards.

This guidance identifies the specification and test requirements and minimum markings to be found on all EN74-1 scaffold fittings. The 2015 update sees no change other than dates. EN74-1 is unlikely to change in the next four years.

This guidance explains the differences between ‘supplementary’ and ‘check’ couplers and gives typical design applications where high coupler forces could be expected and where additional loadbearing capacity to connections may be required. It also contains guidance on coupler configurations and expected safe working loads (SWLs) where supplementary couplers are used. To ensure that SWL values are as accurate as possible, data provided within this document is based on practical testing rather than calculation. 2 pages
