Professional Multi‑Function Layout Square

The RIDGWAY Adjustable Carpenter Square is a professional-grade layout tool designed for woodworkers, carpenters, and tradespeople who require accuracy, versatility, and reliability from a single measuring square. By combining the functions of a traditional carpenter’s square, a double square, and an adjustable mitre handle, it reduces tool changes while improving workflow efficiency.

Adjustable Handle for Repeatable Angles

The adjustable handle pivots smoothly from 0° to 45° and locks firmly in place, making it ideal for repeatable angle marking across a wide range of tasks. Whether working on joinery, trim, cabinetry, or general carpentry or roofing construction, the square delivers dependable results on both site and in the workshop.

Tru‑Mark Edge for Accurate Line Placement

RIDGWAY’s Tru-Mark Edge removes offset errors by placing the marking line exactly where intended, eliminating guesswork and speeding up layout work. An integrated pencil saddle notch supports consistent line placement, helping to maintain accuracy even during repetitive marking tasks.

Stable Reference and Double Square Functionality

A built-in shelf stabiliser lip provides a solid reference surface against the workpiece, meaning the square will stay in place rather than dropping off the timber. This improves control when marking boards, panels, and structural materials. The 203mm sliding ruler allows the tool to function as a double square, adding further versatility for depth setting and shoulder line marking.

Durable Construction with Expandable Compatibility

Manufactured from high-quality anodised aluminium, the RIDGWAY Adjustable Carpenter Square is engineered for durability, stability, and long-term precision. Its expandable platform allows the ruler to be changed to fit optional 102mm, 152mm and 305mm Red Tail Rules to suit individual working preferences, ensuring the tool remains adaptable as workshop needs evolve.
