Stanley Adjustable Quick Square 170mm

Achieving accurate cuts and precise angle transfers shouldn't require juggling multiple bulky layout tools. The Stanley 170mm Adjustable Quick Square solves this by integrating four essential measuring instruments; a rafter square, adjustable bevel, protractor, and saw guide into one reliable, compact package.

Built from heavy-duty aluminium, this square provides the structural stiffness required for professional carpentry and timber framing without adding unnecessary weight to your tool belt. The precision-engineered adjustable arm allows you to dial in custom angles effortlessly, making short work of non-standard roof pitches, compound angle transfers, and repeated bevel markings. Once set, the locking mechanism prevents slip, giving you clean, consistent reference lines every single time.

Readability is critical on fast-paced work sites where lighting can be unpredictable. Stanley tackles this challenge with a high-contrast design featuring a black body accented by sharp yellow graduations. Whether you are working indoors under dim site lights or outdoors in direct sunlight, the bold scale remains clear and legibly defined.

For roofers and framers, the square comes pre-marked with specialised Common, Jack, and Hip & Valley scales, eliminating tedious calculations when setting rafter pitches. Additionally, the thick edge profile functions seamlessly as a fence for circular saws, allowing for fast, true 90-degree and 45-degree crosscuts without the need for additional straight edges. Designed for carpenters, joiners, roofers, and serious DIY enthusiasts, the Stanley 170mm Adjustable Quick Square delivers speed, versatility, and trusted accuracy on every project.
