Gravlock Girder Coupler

There is often a  requirement to fasten scaffold tubes to girders and other steel sections and it demnds a specialised fitting with a high degree of a versatility. The gravlock Girder Coupler has been specifically designed for attachment to either horizontal or vertical flanges, and will accommodate up to 43mm (13/4") in depth. In erection , the gravlock Coupler is highly effective, as it enables the fittings to be bolted to the girder first, leaving both hand free to present and secure the tube. As the tube s not compressed against the girder it is not distorted by the fastening process. Gravlock Couplers must be used in pairs.
