The Astro Pneumatic Memory-Flex Hose Clamp Pliers, No. 9419, are built with a memory-flex cable that stays in the desired shape while in use. The pliers offer a double-gear lock lever, as well as wide, deep gears, a thick cable and a cable length adjuster. This tool allows for the removal of plastic and/or metal self-tightening hose clamps, with diameters of 11/16" through 2-1/2" (18mm to 54mm). The precision clamp on each end of the flexible cable allows for extended reach. These pliers can be locked into position, which frees up hands.
