Made from fibreglass and nylon resin, these folding rules are tough and compact. Their mechanisms have been tested to withstand 25,000 folding operations with no signs of wear. 

They feature spring-loaded stops to click the sections in firmly at 0 degrees (when folded), 90 degrees and 180 degrees. They can't flop around while in use, and require a deliberate action to close them up after everything is measured.

These rulers are non-conductive, unlike measuring tapes.

Each section is 3.2mm thick and 15mm wide. Folded length is 23cm.
