Where to Buy

Lay out pole-drilling measurements faster with a 6-foot inside-read lineman ruler that makes the center easy to find and folds down to 8 inches for the bucket.

Features & Benefits

  • Find the midpoint quickly: Red center-point markings show the center of a measurement without extra math—ideal for pole-drilling layouts.
  • Read from the inside edge: Inside-reading graduations support precise layout work against poles and other surfaces.
  • Measure from either side: Black engraved markings appear on both sides and both edges in 1/16-inch increments.
  • See markings clearly: High-contrast black graduations stand out against the bright green ruler body.
  • Carry a full 6-foot rule compactly: The ruler extends to 72 inches and folds to 8 inches for storage in a bucket or tool bag.
  • Built for field use: Glass-reinforced nylon helps resist weather and daily wear, while engraved graduations improve abrasion resistance.
  • Hold each section in position: Positive-locking joints and corrosion-resistant stainless steel spring hinges provide dependable reach and alignment.

Built for Pole Layout and Drilling

Use the black scale to measure the full distance, then match that number on the red scale to locate the center point. The inside-read layout, double-sided graduations, and folding design make this fiberglass folding ruler a practical choice for concrete-pole drilling and everyday utility measurements.

Frequently Asked Questions

What is an inside-read folding ruler?

An inside-read folding ruler places the scale for measurements taken against an inside edge or surface. The MPFR-6 uses this layout to make pole and jobsite measurements easier to read accurately.

How long is the fiberglass folding ruler when extended and folded?

The ruler extends to 72 inches, or 6 feet, and folds down to 8 inches for compact storage in a bucket or tool bag.

What are the red center-point markings used for?

The red center-point scale helps locate the midpoint of a measurement quickly. Measure the full distance on the black scale, then find the matching number on the red scale to identify the center for drilling or layout work.

What measurement increments are shown on the ruler?

Measurements are graduated in 1/16-inch increments on both sides and both edges. The graduations are engraved to help them resist abrasion during field use.

What is the folding ruler made from?

The ruler body is made from glass-reinforced nylon for durability and weather resistance. Its positive-locking joints use corrosion-resistant stainless steel spring hinges.
