The Milwaukee M18 FUEL Coil Roofing Nailer Replacement Rubber Wear Pads serve as a replacement for the 6 rubber wear pads positioned throughout the tool. These rubber wear pads have a dual purpose of protecting the Roofing Nailer from the abrasive surface of asphalt roofing shingles as well as providing extra grip to prevent the tool from sliding off the roof on higher pitched roofs. These rubber wear pads can be secured in place by T15 / slotted screws for easy attachment and removal. This accessory is only compatible with the M18 FUEL Coil Roofing Nailer (2909-20).
