Girder Clamps

About

Doughty girder clamps create certified rigging and suspension points on structural steel I-beams and H-beams without drilling. Used across theatre grid installations, TV studios, exhibition halls and permanent venue installs where truss or lighting bars must be suspended from existing structural steelwork. This range also covers Gravlock couplers, marquee clamps, saddle clamps, scissor clamps and stud hangers for every structural attachment application.
