EQUIPMENT + TECHNOLOGY Ratcheting Spline Combination Wrenches Proto introduced a new line of full polish chrome, reversible ratcheting combination wrenches with spline box ends; featuring a new open end configuration which allows up to 13 degrees additional swing. The offering includes 38 fractional and metric sizes as well as four wrench sets. Visually distinctive, the new wrench pattern features a patented I‐beam design that removes material weight while offering an increased bearing surface to help improve comfort and reduce hand fatigue. Like most Proto combination wrenches, the open end features an anti‐slip design, locking the wrench onto the fastener head to help prevent injury from wrench slippage. The new line has a 72‐tooth design, re‐ sulting in a 5‐degree arc swing. Fractional sizes range from ¼ in. to 1 ¼ in. and metric sizes from 6 mm to 32 mm. Proto Industrial Tools, Tarp Storage East Manufacturing Co. introduced a new time sav‐ ing and safety option to their drop deck trailers – an all‐aluminum tarp storage box built into the floor of the upper or lower deck. This on‐deck ac‐ cess location reduces multiple ups and downs on the trailer (lessening the chance for falls) to tarp the load, or store the tarp and tie‐downs, which saves time and energy for both tasks. The tarp stor‐ age boxes are available in various depth configura‐ tions, depending on the drop at the neck and beam depth of the drop deck trailer, and can be placed in either the top deck, bottom deck, or both decks. Di‐ mensions of the upper deck storage boxes are 35‐ in. long x 13‐in wide (maximum 22‐in. deep). Lower deck box dimensions are 49 ½‐in. long x 42 ½‐in. wide (maximum 21‐in. deep).
