Pony 1/2-Inch Pipe Clamp Fixture
The Pony 2-1/2-Inch Pipe Clamp Fixture allows you to make bar clamps of any length with a 1/2-inch pipe (not included). No holes, notches, or rivets are required to assemble; just screw the head onto regular pipe threads.
The multiple-clutch system is constructed of plated hardened steel that grips the bar automatically at any point. The clamp faces are 1-1/2-inches-square with a baked enamel finish.
