[Package Includes] 1 x 0.24inch (6mm) roller, 1 x 0.79inch (20mm) roller and 1 x 1.57inch (40mm) roller. 3 sizes of rollers meet different needs. Use the larger roller for longer flat sections and the smaller ones for tight corners such as curves, center console and pillar areas. [Raised Design] Sound deadening roller features a raised design to enhance adhesion. The textured profile improves handling and prevents slippage. The roller smoothly glides across surfaces and firmly presses sound deadening material onto vehicle panels. [Thickened & Solid Metal Roller] Made with high-quality metal wheel, riveted steel roller supports and built-in steel bearings for smooth and quiet operation. The thickened solid construction ensures full and tight contact with surfaces, improving adhesion of sound deadening materials, tapes and patches. Compared to plastic, wood or polyurethane rollers, the metal wheel delivers superior performance. [Secure Connection & Ergonomic Handle] Features a compact structure with secure connections. The short, ergonomic handle allows for easy operation and access to hard-to-reach areas of the vehicle. Designed as a tool for installing soundproofing and sound deadening materials in automotive applications. [Multipurpose Use] Suitable for all types of soundproofing mats, audio insulation and damping materials. Ideal for applying car insulation throughout the vehicle.
