The Lufkin X46 'Red End' model is a quintessential American carpenter's tool, prized for its robust hardwood construction and innovative brass slide extension. Manufactured in Saginaw, Michigan, this 72-inch folding rule became an industry standard for its ability to provide precise interior measurements for windows and door frames.

What Is Lufkin X46 Extension Rule Worth?

The typical price range for Lufkin X46 Extension Rule is $15 - $17 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

  • Condition of the brass slide, including its ability to move smoothly without excessive corrosion.
  • Legibility of the black graduations and red markings on the hardwood surface.
  • Tightness of the folding joints; loose or wobbly hinges significantly decrease the tool's utility and value.
  • Presence of original patina versus damage from moisture or heavy job site wear.

How to Identify Lufkin X46 Extension Rule?

  • Look for the distinctive 'Red End' paint on the tips of the folding hardwood sections.
  • Verify the presence of the 6-inch graduated brass slide extension housed within the first section.
  • Check for the 'Lufkin' and 'X46' model stamps, typically located near the first joint.
  • Confirm the use of strike plates and spring joints made of steel to ensure it is an authentic mid-century model.
