Tool
Rotary laser / pipe laser
Projects long-distance level or elevation lines for hanger layout, sleeves, rack coordination, and long duct runs.
What it means
Keeps long runs from slowly walking uphill/downhill when tape and torpedo levels are not enough.
Check
- Long straight duct runs, hanger elevations, multi-bay layout, equipment pads/curbs, and repeated rod heights.
Warnings
- Do not ignore approved benchmarks, control points, slope requirements, or grid references just because the laser looks clean.
