Long measurements can have caliper accuracy, too.

When you’re measuring inside openings, outside dimensions, stopped grooves, or matching parts, the hard part is not always reading the scale. It’s holding the exact start and stop points without guessing.

Woodpeckers Cal-Zilla turns your Woodworking Rule into a large-format caliper.

Add the fixed and sliding jaws, lock the measurement, and capture inside, outside, or center-to-center hole dimensions with more control than a rule alone.

• Adds caliper jaws to Woodpeckers Woodworking Rules
• Measures inside or outside dimensions up to 46" with a 49-1/2" rule
• Sliding jaw rides on low-friction UHMW glide strips
• Hole Center Attachments measure center-to-center hole spacing
• Precisely machined and carefully inspected in Strongsville, Ohio
