Made of CNC machined heat-treated hard-anodized orange aluminum. They have been engineered to work with DW’s growing fittings offering. These high-grade AN wrenches have chamfered edges to fit comfortably in your hand. The adjustable wrench is ideal for use in the shop, in the pit, or the staging lanes – it fits AN -4 to -16. Aluminum Vice Jaws are ideal for assembling AN hoses and fittings. Buy them separately or as a complete set, they are the best insurance against scratching the finish of your DW Titanium fittings while assembling.
