The Monument Sweatbox is designed for plumbing and heating engineers to easily solder joints on 8-28mm copper pipe, freeing up both hands with its patented clamp. It features an integrated holder for a standard gas bottle, anti-slip rubber feet, and a flux brush holder. Made in Britain from polypropylene with a fire-retardant compound, it also includes designated holes for gas bottles, torches, flux brushes, and other soldering tools.
