A one-piece load bearing coupler incorporating captive T bolts used to connecting two scaffold tubes at right angles.

There are often requirements to fasten scaffolding tubes to girder and other steel sections and it demands a specialized 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.
