The Swivel Clamp Holder by United Scientific is a plated steel double clamp for joining two rods, with one clamp that rotates 360° along its axis and locks in any position. It accepts rods up to 19 mm (0.75") in diameter and measures 4.5" (11.43 cm) across the clamps. Labs use it to set condensers, columns, and extension clamps at angles on ring stands and lattice frames.
