Product Overview

The Bon Tool Seam Roller Inside Radius (19-131) is designed to help installers achieve tight, professional seams in areas where flat rollers can’t reach. With its curved profile, it’s perfect for pressing materials into inside corners, curves, and tight angles—common challenges in flooring, roofing, and wall applications.

Made with a solid wood handle and a durable roller head, the 19-131 gives you the control and pressure needed to smooth seams and eliminate bubbles without damaging material surfaces. It’s often used with vinyl, linoleum, rubber roofing membranes, and wallpaper—any application where material needs to bond firmly to a curved or recessed edge.

This tool is compact, lightweight, and easy to maneuver in awkward spaces, making it a staple for pros and DIYers who need precision seam work.

What It’s Good For

Ideal for pressing seams in inside corners or curved areas, such as where flooring meets the wall, roofing membranes wrap around vents, or wall coverings turn into recesses. Helps create a clean, bubble-free finish where flat rollers fail.

Compared to Other Seam Rollers

Flat seam rollers work well on large open surfaces but struggle in corners. The Bon Tool 19-131 fills this gap, giving you better adhesion and finish quality in tight, rounded spaces where other rollers can’t reach.
