Worksite Rubber mallets are used when an even softer blow is needed and even a wooden mallet might cause damage. The Rubber Mallet is used to form sheet metal, since it is not likely to cause dents, to shift panels of wallboard in place, in upholstery work: For ceramic tile, it helps to gently tap tile into place. Laminate flooring: great for this brittle material and for snugging up joints without damaging pieces. Tap carpeting onto tackless strips. A “sounding device” if you need to hear what is behind a wall or in a pipe. PVC pipe work, to snug up joints. 8oz.
