The CHANNELLOCK 806SW extra-slim, wide jaw adjustable wrench means maximum accessibility. Jaws are 68 percent thinner than most wrenches its size. With a four-thread knurl and non-protruding jaws, the 806SW provides greater capacity while improving performance in confined spaces with its minimal head width. Constructed with chrome vanadium steel for durability, and with precision-machined jaws, the 806SW grips tight the first time, every time. Super-wide opening lets you tackle big jobs with a compact wrench.
