These optional magnetic cursors fit onto the blade of the Bridge City AS-24v3 Adjustable Square.
Attached using built-in rare earth magnets, they are easy to adjust; they stay put, and are easily removable when not needed. They allow you to reference individual graduations to speed up layouts.
Made from anodised aluminium, the cursors have 2 laser-etched edges, bevelled to minimise parallax error. One edge has a centre line with millimetre graduations on either side. The opposite edge features a centre line with a pencil notch. The notch lets you accurately mark with a pencil or allows you to use the square as a panel gauge.
