Why customers choose TaskHolt Tools

Speed meets precision with Johnson’s Johnny Square MACH-1 rafter square with level vial—a pro-grade tool built for layout, marking, and scribing tasks where accuracy matters. The solid aluminum body with CNC-machined edges carries a matte black finish that reduces glare and resists rust, so the ruler stays readable and durable on tough job sites. Its 7-1/4in reach lets you span the full width of common 2x stock, while 1/16in scale graduations keep readings crisp as you work.

What sets MACH-1 apart is the Smart Mark Cutout, a thoughtfully designed feature that delivers clearly identifiable marks for essential layouts and cuts. The tool ships with markings tailored for framing tasks: layout of 1X, 2X, 4X, and 6X lumber, LVL layouts, and common blocking or post sizes. Additional slots support 22.5°, 30°, 45°, and 60° angles, while V-notches at roof pitches help align pencils for top cuts with confidence. These marks are designed to speed up workflows without sacrificing clarity, so you can move from measuring to cutting with less hesitation.
