Woodpeckers Rule Hook
Long rules are great, but when you need to line one end up with an edge as well as reading or marking a dimension without parallax error, things can be a bit tricky.
The Rule Hook overcomes this problem by simply attaching to the zero end of the rule with two set screws into the precisely pre-drilled and tapped holes in the new 1280mm Precision Rule (soon to be incorporated into the 300, 600 and 900mm rules). You then have the ultimate measuring device for long or awkward work pieces.
Please remember these will only work on rules supplied after August 2011.
