The manual edge bander is the ideal solution for the consistent production of high-quality vertical seams such as miter aprons, butt seams, and compound corners without the need for tape or crimping pliers. This tool features 90-degree and right-angle crimpers that can be reversed for inner corners, with unique non-marking cups using flexible triple-seal technology to lock in vacuum for optimal retention on textured and leather materials. Evenly rotating knurled rollers bring parts together for professional alignment, and micro-adjustment levels help adjust the perfect angle for precise seams, while a built-in counter-pressure leveler solves vertical lifting issues. An indicator light monitors vacuum pressure, allowing suction cups to be pumped again without losing residual pressure, unlike button or rocker suction cups; it is sold separately and not for use with porous materials or heavy laminates. Wide range of uses, suitable for precision grouting and leveling of smooth surface materials such as marble, granite, floors, mirrors, glass, and plastics.
