ABSTRACT:
An adjustable clamp for supporting guard rails or the like or an I-beam side rail of a scaffold system comprises lipped flange members designed to overlap the inner edges of end flanges of the I-beam side rail. The flange members each have a U-shaped outward extension and the extensions are joined together by a web means which is adjustable to permit the flange members to engage both I-beam end flanges snugly. A fastening means passes through the web means and bears against the web of the I-beam. Apertures which pass through the flange members serve to securely support posts for a guard rail or the like.
