There are often requirements to fasten scaffolding tubes to girder
and other steel sections and it demands a specialised fitting with
a high degree of versatility. The Gravlock Coupler has been
specifically designed for attachment to either horizontal or vertical
Flanges. In erection the Gravlock Coupler is highly effective as it
enables the fitting to be bolted to the girder first. This leaves both
hands free to present and secure the tube. As the tube is not compressed against the girder it is not distorted by the fastening
process. Gravlock Coupler must be used in pair.
