This is a common tool that is frequently used to adhere plastic laminates and other countertop material. It features a 1-1/2" dia. x 3" wide non-marring rubber roller with a 10" handle and vinyl grip. This item is used when adhering copper veneer to substrates with contact cement.
Extra Note From Joe
Unlike the typical J-roller found at many woodworking supplies and home centers, the handle on this tool is made of solid aluminum. You'll notice right away that this is a much heavier duty tool that wont break like the hollow aluminum version.
