Any size rule slide attachment

Use customizer to custom fit to any size rule.

This can measure length of 2 random points such as the back of picture frames, extension leads, towel rail etc.... and transfer the hole centers to wall for drilling.

It also can be used as a height gauge / comparison. Please note if using as a height gauge make sure your rule graduations start from the datum edge and not as a ruler does which start slightly in from the datum edge. (that's the difference between a "rule" and "ruler")
