LaserLine Quad 100 Precision Plumb Laser

Long-Range Self-Leveling Plumb Laser for Vertical Alignment

The LaserLine Quad 100 Precision Plumb Laser is a long-range, self-leveling precision plumb laser engineered for accurate vertical alignment in construction, industrial, and structural applications. Designed for elevator shafts, high-rise buildings, towers, smoke stacks, and tank alignment, the Quad 100 delivers reliable plumb control where consistent vertical reference over extended distances is critical.

Precision Performance & Jobsite-Ready Design

The Quad 100 provides ±1/32 inch accuracy per 100 feet with a plumb-up working range of up to 1,200 feet, supporting precise vertical layout and verification in demanding environments. An electronic servo self-leveling system with temperature compensation maintains accuracy across varying jobsite conditions, while the integrated plumb-down laser enables fast, accurate positioning directly over reference points. Built for harsh construction and industrial use, the Quad 100 features a rugged, IP65-rated dust- and water-sealed housing, intuitive LCD interface, long battery life, and standard tripod compatibility for dependable field operation.
