Woodpeckers DSQ-STM-20 in-DEXABLE Double Square – Standard – Metric – 150Mm Blade

Key Features

Accurate Parallel Scribing Laser-cut scribing guides along the blade help capture a pencil tip cleanly for repeatable parallel layout work. That saves time when you need consistent marks on cabinet parts, shelves, or trim stock. Indexable Double Square The Woodpeckers double square uses a spring-loaded index pin so you can lock the head at full measurement positions before marking. That gives you a true reference point on an adjustable layout tool. Built For Shop Use A stainless steel blade and machined aluminum head are made for daily layout work without the rust worries of cast iron. The included Rack-It keeps it protected and easy to grab between setups.

Overview

The Woodpeckers DSQ-STM-20 in-DEXABLE Double Square – Standard – Metric – 150Mm Blade is a precision layout square for woodworking and shop setup. This is a double square designed for measuring, checking 90-degree references, and parallel scribing. Model Number: DSQ-STM-20. If you want a layout tool that does more than basic checking, this one is built to mark repeatable lines, hold a setting securely, and stay easy to read over the long haul.

What makes this square different is the way Woodpeckers handled the scribing function. The blade uses laser-cut scribing guides that let you run a pencil along the tool for accurate parallel marks. On an ordinary adjustable square, that kind of work can get fussy because the moving head makes the reference point less obvious. Here, the spring-loaded index pin lets you lock the head at full measurement positions so your starting point is defined before you start marking.

The head design is also more thought-out than the usual adjustable square. Woodpeckers added a sliding head support so the square stays positioned on the edge of the stock without fighting you during layout. In real use, that matters when you’re marking cabinet sides, shelf parts, face-frame stock, or machine setups and you want the tool to stay planted instead of shifting while your other hand is holding the pencil or the workpiece.

Material choice is a big part of why this tool stands out. The blade is stainless steel with deeply engraved markings designed not to wear off, and the head is machined from aircraft grade aluminum rather than cast iron. That gives you a square that is sturdy in use but still lighter than many traditional adjustable squares. The anodized head also avoids the rust issues that can show up in humid shops or jobsite storage.

The 150 mm, or 6 inch, blade size puts this standard double square in the sweet spot for close-in layout and inspection work. It is compact enough for bench work, checking machine tables, setting cutter heights by reference, verifying drawer parts, and marking joinery locations without dragging around a long blade you do not need. For trim details, casework, and furniture parts, that shorter format is often the one you reach for first.

Woodpeckers also includes a wall-mountable Rack-It with individual squares, which is a small detail that matters more than people think. Precision layout tools work best when they have a dedicated place instead of being buried in a drawer with other metal tools. Keeping the square visible, protected, and easy to grab helps it stay accurate and actually get used.

This metric Woodpeckers double square is a strong fit for cabinetmakers, furniture builders, serious hobby woodworkers, and anyone who does repeat layout work at the bench. If your work depends on clean reference lines and reliable setup, it earns its keep fast. If you just need a rough framing square for general construction, this is more tool than you need. But if you care about accurate layout and repeatability, this is exactly the kind of square that makes everyday shop work smoother.

Pro Tip

When you are using the scribing guides for parallel lines, depress the index pin and lock the head at the measurement you want first. That gives the adjustable head a fixed reference so your marks start where you expect instead of drifting during setup.
