Matthews 3/8in Bolt Aluminum Grid Clamp

About: Matthews 3/8in Bolt Aluminum Grid Clamp

Matthews Studio Equipment is proud to introduce its first Aluminum Grid Clamp collection, engineered for the demanding environments of live production, cinema, and television. These lightweight aluminum clamps make rigging faster and logistics easier without compromising on the legendary strength and reliability that professionals have trusted from Matthews Grid Clamps for decades.

Available in four versatile configurations, the collection supports everything from hanging par cans and building pipe grids to complex multi-angle rigging setups. A standout innovation is the Baby Pin model, which is the only aluminum grid clamp on the market to feature a steel baby pin — engineered to resist crushing where all-aluminum designs fail. All clamps mount to 1.5" (38mm) to 2" (51mm) OD pipe and feature a professional black anodized finish with the iconic Matthews ‘m’ logo.

Matthews Exclusive - Steel Baby Pin in an Aluminum Grid Clamp

Under repeated load cycles or overtightening, aluminum pins can deform, creating a safety risk and shortening the lifespan of the clamp.

Matthews engineers solved this by fitting a hardened steel 5/8" baby pin into the aluminum body. You get the weight savings of aluminum everywhere it makes sense, and the crush resistance of steel exactly where it matters. The pin also features a safety hole, knurled undercut, and 1/4"-20 female thread — all in a package that no other manufacturer currently offers.
