Shock absorbing end caps to protect the level Solid block vials for superior durability and accuracy (0.0005" / in) Precision machined utile surface The 72 in. I-Beam level offers precision leveling accuracy in a robust and durable design. It features durable block vials, instead of standard vials, that provide leveling accuracies of +/- 0.0005 in. and enhanced damage resistance. Each base is designed with V-Grooves for accurate reading on both flat and rounded surfaces, and each end cap is constructed with over-molding for enhanced impact protection.
