The Avenger C4465-1 MP Eye Coupler grid clamp comes supplied with a 28 mm(1 1/8\") junior receiver. This popular MP cheeseboro clamp has a wider clamp range than the LP clamp and is ideal for many rigging systems, truss and entertainment configurations. The lower jaw has a special flattened shape which helps in the sizing of this clamp and the increased flexibility to clamp down on different types of tubing. Capable of holding up to 300 kg/661.4 lb loads this clamp will perform in many demanding environments. The MP Eye Coupler uses a wing nut with washer locking design and is able to clamp down on round tubes, truss or grids ranging from 42 mm(1.65\") to 52 mm(2.04\") and is 50 mm(1.96\") wide.
