Lightweight Anodized Stair Gauges

Each stair gauge is precision-machined from anodized aluminum alloy, measuring 2.5 inches long and weighing only 42 grams. Their low mass ensures no added strain during extended layout sessions, while the anodized surface delivers lasting resistance to oxidation and abrasion. Recessed alignment slots correspond directly to standard framing square inch and fraction markings, enabling unobstructed line-of-sight to reference points during marking. A built-in wire rope connector links both gauges securely, supporting compact hanging storage on tool racks, workshop walls or portable job boxes. Used extensively in UK stair-building regulations-compliant projects, they enable accurate tread-to-riser ratio replication across multiple stringers. For roofing applications, they assist in consistent plumb and level line transfers onto rafters — essential for meeting Building Regulations Part A (Structure) tolerances. In joinery and cabinetmaking, they guide repeatable square-based cuts for carcass assembly, door framing and panel alignment. Fully compatible with British-standard 600 mm (24") and 300 mm (12") framing squares, including Empire, Swanson and Irwin models commonly stocked by Travis Perkins, Wickes and Toolstation — requiring no adapters or modifications.
