Modular Work Holder Doubles as a Spray Booth FixtureOur modular work holder is just the tool you need when one set of hands is not enough. It holds work steady and in the perfect position for assembly, soldering, detailing, painting and more. Each articulated arm...two with alligator clips and one with long-nose self-closing tweezer...locks with thumbscrew into any location you need on the aluminum rails to perfectly configure the jig for your workpiece. Heavy steel corner bases with padded feet prevent tipping and sliding. Configuration shown measures approx. 7 inches x 12 inches.
