stainless steel beam clamps with 15/16 in jaw opening are used in wet locations with conduit hangers, bridle rings and are tapped on their bottoms for 1/4-20 rods and bolts. Their threaded backs and bottoms allow for versatility in design. Additionally, their hardened cup point screw and heavy gauge steel body will not distort when tightened on the beam. Their stainless steel body will not corrode in damp, wet or corrosive locations.
