This beefy rule combines several really handy scales into a single stout package. One side features a +/-6" centering rule that's perfect for locating the middle of boards up to 12" wide plus a conventional 12" scale.

On the flip side, there's a 0 to 50 degree bevel scales that works great for accurately setting angles on a sliding T-bevel, or in some cases, marking lines directly onto your work from the edge a board.

There's also a 3" scale printed up the end of the rule, which is ideal for comfortably setting the heights of router bits and table saw dado sets. It's a big improvement over standing a rule on end or trying to hold a tape measure upright and in position while you make adjustments to the machine.

This is a much nicer rule than you'd expect for the reasonable price. It's nicely finished with clean edges and crisp markings over a matte satin finish. Constructed from heavy 0.050"-thick steel, this rule measures 12-1/2" x 3" overall.
