Fuller PRO Pipe wrenches are designed for heavy duty trade use. The range is constructed of drop forged alloy steel for maximum strength and durability. The rounded handle is designed for maximum comfort in high torque situations and the adjusting nut allows smooth movement for fast and secure fitment. The jaws are heat treated for maximum strength and the precision milled teeth give agressive bite to minimise slipping. As with all Fuller PRO products there is a no questions asked lifetime guarantee.
