Introducing the new Smart Ruler! This device allows you to quickly and easily add machined grooves with a router to custom door panels, subwoofer enclosures, amp racks and more! It can also be used to easily sketch a design grid allowing for accurate layout construction.
 
Includes:
Smart Ruler Guide System - 1/4" High Strength Plastic machined with alignment lines and parallel slots
8 metal pins for alignment against the edge of a work piece, the smart ruler can be flipped for adding additional lines between the lines from the previous side. In other words you can sketch a grid system using the first side of the ruler which will create lines with 1" spacing, you can then flip the ruler and the offset pins will now align the slots so that you can sketch additional lines between the existing lines, now giving you a 1/2" grid.
 
Use in conjunction with the Template Guide System to machine perfect grooves into your build!
