Hook rules allow you to accurately measure from the edge of your workpiece. Simply slip the hook over the edge of your work, and your rule is instantly and perfectly registered. The removable hook can be secured to either end of the rule or removed entirely when not needed.

Each rule is machined from aircraft-grade aluminum and then black anodized for exceptional resistance to wear, corrosion, and friction. Both edges of the blade are beveled to 30 degrees to reduce parallax viewing errors and ensure precise marking. The backs of the blades are recessed to allow the rule to sit flat against your workpiece.

Each rule measures 2-1/4" wide by 1/4" thick and includes hanging holes for convenient storage.

Bright white laser-engraved graduations stand out clearly against the black anodized surface, making them easy to read—even in low light or for users with aging eyes. One edge of the blade features 1/16" increments, while the opposite edge is marked in millimeters.

All corners and edges are gently eased, making the tool comfortable to hold and use.

These hook rules are available in multiple sizes: 12" (300mm), 24" (600mm), and 36" (900mm).
