Adaptive Technologies Group MC-030 Truss Clamp with M12 Eyenut (Silver)The MC 030 is created from high tensile, aircraft grade, extruded aluminum; so its both stronger and lighter than cast iron clamps. The MC 030 fits from 1 pipe to 2 pipe sizes (1 15 16 OD to 2 inch OD tubes.) This means you can hang fixtures from a 2 pipe without having to buy an expensive Heavy Duty Clamp. The MC 030 fits the larger pipe standard. Specifications SPECIFICATIONS PACKAGE CONTENTS Color: Silver 1 pc MC 030 BT Truss Clamp Finish: Aluminum
