Single Rounded Seam Roller

Purpose-built for tight detail work, the MR13500 uses a lightweight, corrosion-resistant aluminum V-profile wheel that nests into inside corners, ribs, and channels where flat rollers can’t reach. The V shape focuses pressure right in the angle for crisp, uniform consolidation on single-ply membranes, while a rigid frame and smooth bearings keep tracking precise and chatter-free. Comfortable in hand and tough enough for daily use, it’s a go-to finisher for corners, step-downs, and...

Built for smooth finishing with a wider contact line, the MR08580 uses a 1/4″ rounded (convex) steel wheel to deliver even pressure without imprinting sharp track lines. The curved edge lets you blend seams, patches, and step-downs cleanly, while a rigid frame and enclosed bearings keep the roll precise and chatter-free on TPO, PVC, and EPDM. Key Features 1/4″ rounded/convex steel wheel spreads pressure for faster blending and fewer visible edge marks Ideal for dressing long seams,...

Built to finish tight corners and change-of-plane details fast, the MR13115 puts two aluminum V-profile rollers on a single tool so you can switch tasks without swapping tools. The V shape nests neatly into inside angles, ribs, and step-downs, focusing pressure exactly where a flat wheel can’t reach. Lightweight, corrosion-resistant aluminum keeps fatigue low and heat transfer stable during hot-air weld finishing, while the rigid frame and smooth bearings deliver precise, chatter-free...

Designed for precise seam finishing with a touch more coverage than ultra-thin detail rollers, the MR08530 uses a 1/8″ rounded (convex) steel wheel to deliver controlled, even pressure without leaving harsh track lines. The curved edge lets you run right up to laps, transitions, and change-of-plane details, while the rigid frame and smooth bearings keep your passes steady and chatter-free on TPO, PVC, and EPDM.Key Features 1/8″ rounded/convex steel wheel for clean consolidation with minimized...

Built for precision in tight corners and change-of-plane details, the MR13110 uses a solid brass V-profile wheel to deliver firm, even pressure exactly where flat rollers can’t reach. The V shape nests into inside angles, ribs, and step-downs to help you consolidate seams cleanly without scuffing adjacent surfaces. Paired with a rigid frame, smooth bearings, and a comfortable handle, it’s a go-to finisher for detail flashing on TPO, PVC, and EPDM. Key Features Brass V-profile roller focuses...

Built for ultra-precise finishing, the MR08500 uses a super-narrow, 1/16″ rounded-edge wheel that reaches where standard rollers can’t. The curved edge helps you ride right up to a seam or change-of-plane without leaving hard track lines, while the slim profile concentrates pressure exactly where you need it. Smooth bearings and a rigid frame give you controlled, chatter-free passes on detail flashing for TPO, PVC, and EPDM. Key Features 1/16″ rounded-edge wheel focuses pressure into tight...
