Engineered specifically for the high-intensity demands of the structural steel and fabrication industries, the Klein Tools 55665 Tradesman Pro™ Ironworker and Welder Backpack is more than just a tool bag—it is a customized mobile workstation. Constructed with NFPA701 compliant 1680d ballistic weave and rugged leatherette, this backpack is built to withstand sparks, slag, and the brutal conditions of the jobsite. With a massive 50-pound load capacity and a fully molded waterproof bottom, your expensive precision tools stay protected from sharp edges, mud, and the elements, whether you are on a skyscraper deck or a shop floor.

Organization meets innovation with 27 specialized pockets designed for unique trade tools. This backpack solves the industry’s biggest transport challenges by providing dedicated space for a 24-inch to 36-inch connecting bar, custom interior straps for spud wrenches, and a reinforced pocket for a 6 lb hammer.

Pro-Tip: To extend the life of your backpack, take advantage of the removable front pocket. After a heavy week of welding, remove the pocket and shake out the metallic dust and slag before it works its way into the zippers. Keeping the zipper tracks clear of debris will ensure the aircraft cable handle and lockable pulls stay functional for years.
