Portable, foldable angle ruler that speeds up layout and cutting work while keeping measurements accurate and repeatable. Key benefits Save time: fold-and-go design replaces slow template-making so you can transfer angles quickly and move between jobs. Better accuracy: the clip-on level helps you set and check plumb and horizontal references for more reliable measurements. Long-lasting precision: dual metric/inch scales are permanently engraved into the aluminium alloy so numbers won’t wear off. Stable locking: adjustable screw tightens to hold any angle firmly for tracing or cutting and records the exact marking for repeat cuts. Features Material: high-quality aluminium alloy for a stable, rust-resistant tool body. Scale: metric and inch double scale on the ruler body for flexible measurements and international projects. Locking mechanism: simple screw adjustment to set and fix angles quickly. Level: clip-on bubble level improves on-site alignment and reduces rework. Portability: folds compactly for easy transport between work sites or storage in a toolbox. Practical applications Trim and molding: quickly reproduce complex mitre angles when installing crown molding, baseboard, or door/ window trim. Carpentry and framing: transfer rafter cuts, work angles for stair stringers, or mark repeated angle cuts for consistent joinery. Tile and flooring: measure and transfer irregular corner and transition angles to tiles or planks for precise cuts. How to use Unfold the ruler, align one arm with the reference surface, adjust the screw until the other arm matches the angle, verify with the clip-on level, then tighten to lock and mark or cut. Compact, durable, and designed to speed layout work while keeping measurements accurate and readable.
