- The attractive filigree design of these levels provides a lighter weight, and the curved design evenly dissipates excess heat
- The base of the levels has an involute groove running the full length, which provides a reliable seat for round work
- All sizes have a main vial and double plumb vials. Each vial has two graduated lines
- The main vials have approximately 19-minute sensitivity, meaning if the bubble moves 1/8" off the graduated lines, the out-of-level is approximately .080" per foot. If the bubble is off 2mm, then the out-of level is approximately 4.4mm per meter.
