Slide the Grate-Fast™ clamp towards the steelwork until the nose fits under the beam flange. Where necessary adjust the body/screw to the approximate flange thickness/grating depth.
Tighten capscrew using the hexagon key. Grate-Fast™ body casting will automatically rotate until it locks under bearing bar, with nose under flange. Continue tightening to the recommended torque. Grate-Fast™ is now secure.
