Strap wrenches provide gripping power without scratching or deforming plastic or polished metal pipe. Aluminum handle lessens the weight of the wrench. Use on plastic pipe, filters, or any slick or smooth surface. Strap wrenches work well on irregular shapes, too. Reed’s coated polyester strap provides slip resistance and durability. AS W12A30 and AS W18A48 feature extra-long straps for increased leverage on large diameters.
