Light and strong, the titanium-aluminum alloy handle of the Aluminum Pipe Wrench is heat-treated for maximum strength. Reed aluminum pipe wrenches offer tighter tolerances for a snugger wrench, ''beefier'' housing for a stronger wrench, and textured paint for a better grip. Note: Reed aluminum pipe wrench parts are interchangeable with most major U.S. brands (including RIDGID®) of straight, 45 deg offset and end wrenches from 18 to 48 in. Parts available include hook jaw, heel jaw and pin, coil and flat spring, and nut.
