This connector is ideal for laboratory lattice frames and other semi-permanent installation. The grip size is 0 to 13 mm (0 to 0.51") and perpendicular alignment is assured. Two set screws are included. Available in nickel-plated zinc or stainless steel.
Another popular alternative that effects the same connection is our Laboratory Frame Connector (item # 22030) which has no protruding screws to snag on shirt sleeves, cords or equipment.
