LongLife Folding Rules

These are folding rules for the 21st century. Made in Switzerland from fiberglass-reinforced polyamide, they are strong and lightweight, and will never warp. They won’t bend or twist like a tape measure, so you can hold either rule at any point along its length without needing to support its ends, helpful when working alone. You can mark the rule surfaces with a pencil, allowing you to use them like story sticks for direct reference. Each joint is spring loaded for constant tension, with detents that hold the rule in the open or folded position. The black-filled markings are deeply incised, and you can register a pencil tip in them when the rules are used on edge.
