The handiest roller of them all. Theses rubber "J" rollers are soft enough to avoid marring but firm enough to smooth out all covering materials, and are conductive enough to prevent static build up. Up to 50 lb per square inch can be applied to assure thorough bonding of the adhesive layer. Since there are no axle protrusions on the open end, you can roll close to uprights without danger of marring. Light weight with Comfort Grip handle, it is easy to use and to carry.
