The Starrett 135A Pocket Level is a compact, precision spirit level built for machinists, tradespeople, and tool room professionals who need accurate horizontal readings on the go. At just 2-1/2" (63mm) in length, this pocket-sized level delivers the trusted accuracy Starrett has been known for since 1880.

Key Features:

• Compact 2-1/2" (63mm) length — slips easily into a shirt pocket, tool belt, or apron
• Hexagonal brass body with smooth convex ends — no sharp edges for safe, comfortable carrying
• Satin nickel-plated finish — resists corrosion for long-lasting durability
• Single glass vial (main level) — scratch-resistant for clear, consistent bubble readings

• Flat base — stable placement on machinery, workpieces, and surfaces

The 135A is ideal for checking horizontal alignment in machine shops, tool rooms, and light industrial environments. Its glass vial resists scratching and provides clear readings, while the hexagonal profile ensures a secure, non-rolling grip. Whether leveling surfaces, setting up machinery, or checking alignments in tight spaces, the Starrett 135A delivers reliable precision in a carry-anywhere form factor.
