Centre Finder

Centre finder (also known as Center / Centre Sliding Gauge) It can be quickly attached to ANY steel rule….up to a max. of 28mm wide x 1.2mm Thick. [21st Oct 2024] Updated to accommodate larger rulers (now a max. 31mm wide x 2.2mm thick) just be sure to use my print profiles. This is an extremely simple yet handy marking tool.
