Precision-Engineered 6 Inch to 12.5 Inch Extendable Aluminum Rafter Square Layout Tool

The Crescent Lufkin EX6 2-in-1 Extendable Layout Tool operates as a versatile framing and angle measurement gauge engineered to perform the layout functions of both 7-inch and 12-inch rafter squares within a single compact body. Constructed from solid aluminum with a corrosion-resistant rawhide and black finish, this 0.73-pound layout gauge utilizes a 6-inch fold-out extension arm deployed via a quick-release thumb lock to expand measuring reach from 0 to 12.5 inches. Featuring laser-etched permanent SAE scale graduations, the unit fits directly into standard tool pouches, providing precise angle markings, crosscut guidance, and roof pitch layouts on job sites without requiring multiple dedicated framing squares.

Best Used For:

  • Roof Framing & Rafter Layout: Marking rafter hips, valleys, plumbs, and seat cuts across 2x4 through 2x12 dimensional lumber using the 12.5-inch extended arm.
  • Stair Stringer & Angle Layout: Scribing step rise-and-run dimensions, angle transitions, and square crosscuts directly onto framing stock.
  • Compact Jobsite Tool Pouch Carry: Contracting down to a 6.5-inch length footprint to fit inside standard carpenter pouch pockets and tool belts.

Key Performance & Safety Features

  • 2-in-1 Extendable Design: Hinged 6-inch fold-out arm expands the square's capacity to 12.5 inches, eliminating the need for separate 7-inch and 12-inch squares.
  • Quick-Access Thumb Lock Mechanism: Solid-state thumb release deploys and locks the extension arm firmly at 90 degrees for wobble-free layout lines.
  • Solid Aluminum Alloy Construction: Rigid metal body withstands jobsite drops while providing corrosion resistance against weather elements.
  • Laser-Etched High-Contrast Markings: Permanent scale markings are etched into the aluminum face to resist fading from grit, mud, and friction.
  • Compact Pouch Profile (6.5 in. Contracted): Folds down neatly to fit standard belt pouches, eliminating pocket snagging and cumbersome tool belt weight.

Pro-Tip: When deploying the 6-inch extension arm for scribing long cut lines across 2x10 or 2x12 rafter lumber, ensure the thumb lock clicks firmly into its detent. Fully engaging the locking pin guarantees the fold-out arm remains locked rigidly at a true 90-degree angle, maintaining razor-sharp accuracy across wide boards.
