ROBERTS® 6" Pro Loop Pile Carpet Seam Roller is specifically designed to seam loop pile carpets. It hides carpet seams by bringing the fibers together to show as little seam as possible. Extra-wide 6 in. head produces better pile transition over the seam and is optimally sized for use with most brands of seam tape. The steel, star wheel rollers also improve the transfer of hot-melt tape adhesive into the carpet for a stronger seam. This roller is designed with non-marring, recessed hardware to prevent damage to walls and baseboards. It features a longer ergonomic handle for more seaming force and stability, and a textured grip to prevent slipping.
