PRODUCT GUIDE

Choose and use this instrument with confidence.

Keep inch and metric references together on a high-contrast rule.

This black anodized aluminum rule places centimeter and millimeter markings on one edge and inches with sixteenth-inch subdivisions on the other, supporting mixed-unit measurement without changing instruments.

Choose the right configuration

Choose the unit system and length, then select the calibrated edge and reading direction shown from your working position. Available configurations: 20" / 50.8 cm, 40" / 101.6 cm, 60" / 152.4 cm, 80" / 203.2 cm, 100" / 254 cm.

Care, warranty, and returns

Store flat or fully supported so the measuring body, square head, or curve is not bent or twisted. Wipe with a soft dry cloth after use; if a lightly damp cloth is needed, dry the instrument immediately. Lance instruments include a 30-day warranty. Returns are accepted within 30 days when the product is unused.

Choose a ruler length for your working surface

Original schematic. No scale marks or physical dimensions are implied.

Match the usable span, not just the product name

  1. Measure the longest uninterrupted line your job needs and check the depth/width of the supporting surface.
  2. Choose an available length that spans both marks and can remain supported. Check where the selected ruler’s calibrated scale begins and ends.
  3. Check width, thickness, units and reading direction before ordering—especially for a fixture or mounted installation. If a dimension is not documented, ask Lance instead of estimating from the photo.

Longer is not always easier to handle, store or ship. Compare the shipping profile of the exact size you select.

Suitable for / not documented for

Suitable for

  • Dual-system industrial measurement

Check the calibrated edge and reading direction from your working position. Compare orientations; do not assume every black ruler has the same scale or reads both ways.

Not documented for

  • Tolerance-critical inspection: Accuracy and tolerance are not yet documented for this product family and size.
  • Knife or rotary-cutter guide: No cutting-safe edge specification is documented.

Use these guides for pencil/pen marking. Do not run a knife or rotary blade against a calibrated edge without confirmation that the selected SKU is designed for that use. Slip-resistant backing alone does not establish blade compatibility.
