Gravlock Girder/Beam Coupler
There is often a requirement to fasten scaffold tubes to girders and other steel sections and it demands a specialised fitting with a high degree of versatility. The Gravlock girder coupler has been specifically designed for attachment to either horizontal or vertical flanges, and will accommodate up to 43mm (1 3/4”) in depth. In erection, the Gravlock coupler is highly effective, as it enables the fitting to be bolted to the girder first, leaving 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 couplers must be used in pairs.
Safe working load: 30kN per pair (loaded at right angles to the flange)
