Everhard MR12540 - Nylon 'Vee' Roller

Engineered for crisp finishing in tight corners and change-of-plane details, the MR12540 uses a non-marring nylon V-profile wheel that seats neatly into inside angles, ribs, and channels. The V shape focuses pressure exactly where you need it while protecting adjacent surfaces, and the smooth, enclosed bearings give you chatter-free tracking for precise weld finishing on TPO, PVC, and EPDM membranes. A rigid frame and comfortable handle round out a lightweight, jobsite-tough detail roller you’ll reach for all day.

Features

• Nylon V-profile wheel concentrates pressure in angles and grooves for clean, uniform consolidation
• Non-marring, solvent-resistant nylon helps prevent scuffs on finished membranes
• Smooth, enclosed bearings for consistent, low-drag rolling and long service life
• Rigid single-fork frame keeps hardware clear of the contact path for precise control
• Ergonomic 5″-class handle provides a secure grip and knuckle clearance near walls and curbs
• Ideal for corners, step-downs, penetrations, ribs, and other detail flashing work on single-ply systems
• Lightweight, durable construction built for daily professional use
• Made in the USA quality consistent with Everhard’s roofing tool lineup

• Roller size: 2″ diameter × 7/16″ width. 
• Roller material/profile: Nylon V-profile; hubs taper to a 5/64″ rounded edge to help prevent cutting the membrane.
• Forks/frame: Double-fork (single-end) design for stable tracking. 
• Handle: 5″ wood handle. 
• Bearings: Enclosed ball-bearing action for smooth rolling.
• Weight: ~0.344 lb (≈0.156 kg). 
• Country of origin: Made in USA.

• Grip the 5″ hardwood handle firmly, ensuring control over the roller.
• Position the “V” roller tip into the seam, flashing edge, or detail angle you wish to press.
• Roll along the joint using steady, even pressure to press the membrane or adhesion layer.
• Roll backward if needed to reinforce adhesion or close any gaps.
• Use the rounded hub edges to avoid damaging or cutting the membrane.
• After use, wipe off adhesive, debris, or residue from the roller surface.
• Store the detail roller in a dry, safe spot to protect the roller and its bearings.

Q: What is the MR12540 Nylon “Vee” Roller used for?
A: Finishing tight details—inside corners, change-of-plane seams, ribs, and channels—where a flat roller can’t reach. The V profile focuses pressure exactly in the angle for crisp consolidation on TPO, PVC, and EPDM membranes.

Q: What are its key dimensions and materials?
A: It uses a nylon V-profile wheel sized about 2″ in diameter × 7/16″ in width, mounted on a double-fork frame with enclosed bearings and a 5″ wood handle.

Q: Why choose a nylon V roller over steel or silicone?
A: Nylon is non-marring and solvent-resistant, helping prevent scuffs on finished membranes. The V hubs taper to a small rounded edge, which helps avoid cutting the membrane while still delivering focused pressure in corners.

Q: Any tips for use and care?
A: Use light-to-moderate, steady passes; let the V ride the corner without forcing it. Keep the wheel and bearings clean, wipe down after use, and store the tool dry to maximize service life.
