Similar to the H-8950, this clamp has a phosphor-bronze spring clip attached to an aluminum rod-holding block for thermometers and 2 "v" notches designed to hold the H-1602 ring and stem assembly in an ASTM Softening Point Apparatus, but can be used to suspend other items, such as pitch cubes. The maximum distance from the jaw to the muff is 3-5/8" (92mm) and the overall length is 5-1/4" (133mm).
