he Series 2490 Multi Function Stainless Steel Hydrant Wrench has the 4 most common pentagon openings to match the nuts and stems on most fire hydrants. Additionally, it has a water/gas shut off valve tool built into the handle for opening and closing the water and gas valves. The curved handle is designed to accommodate both the 2 1/2 and the 4 inch pin lug hose couplings eliminating a need for another tool to loosen or tighten the hose to the hydrant. The tool provides superior strength, over 170,000 psi tensile with a Rockwell hardness of over 35 making it virtually impossible to break or crack.
