Pin retention sets this grip apart on pipe: beyond clamp compression, a pin adds a second layer of mechanical security, useful where the panel must resist rotation or lateral load on a 1.67" OD Schedule 40 pipe handrail. The rounded Medium Radius body suits a glass stair rail, a ramp or landing guard, or a pipe-handrail glass barrier with dependable glass infill on standard pipe. It accepts either 1/4" or 3/8" tempered glass, so one part handles a range of thicknesses, and is built in 316-grade stainless steel for marine, coastal, and chemical-cleaning environments, in Polished or Satin.
