Pipe laser technology from AGL Construction Lasers, Topcon Positioning, Leica Geosystems, Apache Technologies and AGATEC Construction Lasers.

AGL Construction Lasers
The GradeLight 2700 and 3000 by AGL is the shortest pipe laser available. Its 10.5” length makes it ideal for fitting tight inverts. Applications include sanitary and storm sewers, tunneling, and pipe jacking. The GradeLight Series will self-level over its wide +40% to -10% grade range. It’s powered by a Li-Ion rechargeable battery pack, alkaline batteries, or from a 12V DC source with an optional power cord. For strength, the one piece housing and other components are aluminum die casts and extrusions. The inner mechanism also has die cast parts, adding to its precision and reliability. Besides its durable construction, the GL Series is similar to past GradeLight models by having the broadest range of set-up accessories, as well as adapting to those from previous models. 800.643.9696, agl-lasers.com
