The BULLDOG shower drain wrench, from NCSP, is by far the most innovative tool for the plumbing contractor or building professional involved in bathroom remodeling. It quickly and easily tightens both slip-on (no-caulk) shower drains, as well as the standard IPS thread-on shower drain. Use it to scribe the cut out for the drain body. Made of 1/2" solid steel with a rubber coated handle for comfort and a rust resistant coating. The BULLDOG is uniquely designed to slide between the inner portion of the lower, and upper, drain body and the ABS pipe to tighten the brass ring nut ensuring adequate compression of the rubber grommet. NO MORE LEAKS! The BULLDOG is used by Building, Remodel, Tile and Plumbing Contractors, and even homeowners that demand superior performance from their tools.
