Intended predominantly for engineers and designers, this A4 sized 206-page document provides technical data, commentary, and source material for use by competent and suitably qualified scaffold designers in circumstances which are outside the scope of standard solutions provided in the TG20:13 Operational Guide and TG20:13 e-Guide software.

TG4:19 had amendments predominantly in relation to the orientation of ring bolts where current thinking is that settlement is probably greater than side wind loads so reduces potential shear loads on the bolt. Other minor changes were cosmetic. A recent update in April 2019 saw the removal of one reference only when the guidance was reissued as TG4:19.
This guide considers ancillary scaffold components that are widely used within the UK, but are not currently covered by British or European standards or NASC Technical Guidance. Currently such components are widely available from numerous manufacturers from all parts of the world with wide variations in quality and load bearing capacity. It aims to set minimum acceptable ‘standards’ by providing consistent data for engineers, buyers and component manufacturers to source reliable and fit for purpose equipment for use within the UK industry. 4 pages
This guidance gives details of various products available which will satisfactorily hold down scaffold boards to prevent movement. Users should satisfy themselves that any proprietary system meets their requirements.
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.
