Lockable hole distance measurer (20-200mm)

I always struggled with drilling the holes for wall mounts and pictures. With this handy tool, you can measure the distance between the holes of the thing you want to mount and can lock it in place with the knob. To achieve the perfect pitch, the top of the holes is flat for the placement of a small level.

The little pins can be used to put through the holes, so you can put them into the holes of the thing you want to hang up. The pins can be stored on top of the measurer.

There are three versions available: 20cm, 15cm and 10cm. You'll need one knob, one left piece and a right piece with the desired length.
