Pocket Level with Single Vial

The Starrett 135B is a compact pocket level designed for quick alignment checks. Its 3 1/2 inch steel frame carries one glass level vial readable from the top. The tool fits easily in a pocket or tool pouch for on-the-go use.

For tradespeople needing a simple level.

Carpenters, plumbers and DIY users who want a lightweight level for rough alignment will find this suitable. The standard accuracy of 24 to 30 minutes is adequate for general levelling tasks. Surveyors or machinists requiring finer tolerances should look at precision instruments instead.

Questions about this item

What surface does the 135B pocket level need to rest against for an accurate reading?

Place the steel frame flat against any clean, ferromagnetic or non-magnetic surface; the single glass vial reads level when the bubble centres in the top-read window.

Will the non-magnetic 135B interfere with a traditional magnetic base I already use for layout work?

No, the 135B is non-magnetic so it will not affect a magnetic base or cling to steel shavings while you work.

How do I confirm the 135B is reading within its 24 to 30 minute accuracy after I set it up?

Set the level on a known-flat surface, note the bubble position, flip it end-for-end; if the bubble returns to the same centred spot the vial is within the stated 24 to 30 minute tolerance.
