Lowell Corp. offers a wide array of 100% made-in-the-USA lineman wrenches to make linemen’s toughest jobs easier. The Lowell lineman’s wrenches provide greater flexibility for linemen dealing with the most common nut sizes in pole fasteners, lag bolts, C-clamps and suspension bolts. Our 151T, 150T, 51T and 50T triple square wrenches showcase three socket sizes in one: 3/4-inch-by-1-inch-by-1-1/8-inch squares for 1/2-inch, 5/8-inch and 3/4-inch bolt hardware. Our TDE series are a dual-ended, five-in-one lineman wrench that includes 3/4-inch-by-1-inch-by-1-1/8-inch squares on one end and 9/16-inch-by-3/4-inch hex on the other. These lineman wrenches feature our Bolt-Thru design, which allows long bolts to pass entirely through the wrench head. Our 101 XRS is designed for hardware used in pad-mount transformers. The SETSIS, TSIS and TRTSIS impact sockets include narrow, hollow shafts for long bolts and easy grip. The TSIS has 3 square sizes: 13/16-inch-by-1-inch-by-1-1/8-inch for 1/2-inch, 5/8-inch and 3/4-inch hardware. Our SETSIS contains the same sizes but with a retractable head for faster changes. Our TRTSIS is designed for transmission hardware, with three square sizes in one: 1-1/8-inch-by-1-5/16-inch-by-1-1/2-inch. https://lowellcorp.com/product-category/high-line/
