Pack of five acrylic mini spirit levels measuring 29 x 10 x 12 mm with magnetic bases for hands-free levelling on ferrous surfaces
This set contains five acrylic bubble levels measuring 29 x 10 x 12 mm each. The green square vials are designed for quick alignment checks on ferrous surfaces. They suit technicians and hobbyists who need portable layout tools for machinery or fabrication work.
Each level has a magnetised bottom that adheres to iron or steel, leaving both hands free to adjust the workpiece. The acrylic body keeps the unit light at 29 mm long, so it can stay in position without adding bulk or slipping during setup.
The critical dimension is the 29 mm vial length, which determines the readable bubble travel and the minimum mounting space required. Buyers needing longer bubble travel for finer angular resolution or non-magnetic mounting options should look elsewhere.
Measured against everything we stock in Gauges & Tachometers, at today’s prices. Recalculated every night.
No published specifications for this item yet.
Acrylic vials resist clouding under normal indoor use; store them dry and avoid solvent cleaners to keep the bubble clear for years.
The small 29 x 10 x 12 mm footprint limits magnetic surface area, so heavy vibration or thick paint can break the hold before the vial reads level.
Acrylic tolerates typical toolbox temperatures without warping; prolonged direct sun may gradually fade the green tint but will not affect the vial accuracy.
