This 36" long roller tamp prepares the surface of a slab for a smoother finish. The roller depresses the aggregate and brings the fat to the surface of a slab in a uniform fashion. The 5" diameter roller has a special roller tamp screen to optimize the work. Using this tamp does a better job leveling the slab than other conventional tampers. The tamper can also be used to create a non-skid surface when rolled over for a final finish. Use with a 1-3/8" button handle, sold separately. Use an adapter for use with threaded or 1-3/4" button handles, sold separately. The roller is replaceable to extend the life of the tool. The roller is replaceable to extend the life of the tool; use a 36" Roller (CC954). Proudly made in the USA.
