Crescent Lufkin 646LN Masonry Wood Rule – 5/8 in x 6 ft with Brass Ends

Since 1869, Crescent Lufkin has stood at the forefront of measuring tools and equipment, delivering reliable, precise, and durable lines for professionals and DIY enthusiasts alike. The Crescent Lufkin 646LN Masonry Wood Rule is crafted to handle the rigors of masonry layout tasks while maintaining legible markings and an enduring build.

Designed with a traditional wooden blade, this rule pairs heritage quality with practical features that matter in the field. The brass-plated joints and brass end caps help keep the rule intact after repeated flexing, tapping, and edge contact. The outside edge is graduated along both sides to 1/16 inch, making quick readings straightforward on brick and block work. Inside, six scales arranged in 16-inch modules provide flexible reference points for common masonry layouts, allowing you to map spacing with confidence as you plan courses and joints.

In real-world use, you’ll notice the tactile feel of the smooth wood, the subtle weight that signals sturdiness, and markings that resist fading under bright shop lights or sunlit job sites. This rule suits a range of tasks—from rough layout checks on a masonry wall to precise spacing work during bricklaying or stone work. The combination of traditional craft and practical measurement options helps you work efficiently without rushing a critical step.
