Universal jig for furniture fittings in the near future may receive an additional option - roulette mounting.
On the upper platform of the jig, from opposite ends, marks are placed for installing the jig at a given distance from the edge of the part.
The clamp allows you to firmly fix the tape with a plastic screw.
The clamp of the tape measure is not without drawback - as can be seen in the photo: the ruler of the tape measure is raised above the part plane by 10 mm. (thickness of the jig's upper platform) that must be considered. This nuance can give an error if it is ignored.
