This 18 In. long double roller tamp prepares the surface of a slab for a smoother finish. The two rollers depress the aggregate and brings the fat to the surface of a slab in a uniform fashion. Each 5 In. diameter roller has a special roller tamp screen to optimize the work. Using this tamp will level the slab in half the time and does a better job 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 threaded bull float handle, sold separately. Molded threads on bracket for a secure handle connection. Use an adapter for use with threaded 1-3/8″ or 1-3/4″ button handles, sold separately. Rollers are replaceable to extend the life of the tool; use 18″ Roller (#CC949).
