Matthews Studio Equipment's Baby and Junior Pipe Clamps are built for professional rigging—trusted on sets and stages worldwide. Designed for long-term installation on steel pipe, each clamp features a uniquely molded hook that keeps it safely on the pipe, even while mounting a light or tightening the bolt. The Baby Pipe Clamp terminates in an industry-standard 5/8" Baby Pin with a knurled undercut for secure fixture mounting, plus a safety chain and cotter pin for added peace of mind. The Junior Pipe Clamp terminates in a 1-1/8" Junior Receiver, featuring a precisely aligned safety hole to pair perfectly with standard Junior Pins. Ideal for permanent rigging on grids, trusses, or pipe structures, Matthews Pipe Clamps provide strong, reliable support for heavy-duty lighting and grip gear. For temporary or quick setups, Matthews Grid Clamps are the better choice. Each Pipe Clamp tightens easily with the Matthews Patriot Wrench, engineered for professional rigging gear.
