Key Features
Fast Layout Work Scribing guides on 1/16 inch centers help you lay out parallel lines quickly without juggling spacers or measuring each mark one at a time. Easy-to-Read Blade The satin-finish stainless steel blade uses a laser-engraved scale, so the markings stay clear and readable when you are doing setup, checking parts, or marking stock. Modular Square System This Woodpeckers double square is part of the in-DEXABLE system, giving woodworkers a more flexible setup based around interchangeable rule-and-head style measuring tools.
Overview
The Woodpeckers in-DEXABLE Double Square Standard with 6 Inch Blade and Rack-It, model DSQ-ST-20, is a precision woodworking layout and inspection square built for marking, checking, and setup work at the bench or machine. This is a double square designed for layout lines, assembly checks, and machine setup. If you do cabinet work, furniture work, joinery, or repeatable shop setup, this is the kind of measuring tool that earns its keep fast.
What matters here is how it speeds up accurate work. The blade includes scribing guides on 1/16 inch centers, which lets you strike quick parallel layout lines along an edge without resetting a separate gauge. That is useful when you are marking repeated offsets on case parts, drawer components, face frame stock, or any part where consistency matters more than doing the same measurement over and over.
The blade itself is stainless steel with a satin finish and a laser-engraved scale. In real use, that means the markings are easier to read under shop lighting and more likely to stay legible over time than printed markings. The square head is machined aluminum in Woodpeckers’ familiar red finish, giving you a solid reference surface for checking inside and outside squareness, setting bit or blade height, and transferring dimensions.
The Woodpeckers in-DEXABLE Double Square Standard with 6 Inch Blade and Rack-It is also built around the brand’s in-DEXABLE system. That is important if you want a measuring setup that works as a coordinated system instead of a one-off square. Based on the product imagery, this tool uses the in-DEXABLE platform format and includes the Rack-It wall storage accessory, which helps keep the square protected, visible, and ready instead of buried in a drawer.
On the bench, this double square fits the jobs woodworkers actually do every day. It works for checking assemblies during glue-up, verifying fence and bit settings at the router table, marking lines parallel to an edge, and making quick reference checks before you cut expensive stock. The 6 inch blade size is a practical middle ground for smaller parts and machine setup where a full framing square would just get in the way.
Who should buy it? Woodworkers who care about repeatability, clean layout, and fast setup. If you mostly need a rough carpentry square for framing lumber, this is overkill. If you build cabinets, furniture, jigs, fixtures, or detailed shop projects, this style of precision square makes a lot more sense. It is a measuring and marking tool for people who want accurate results without wasting motion.
Mark Parallel Lines Faster
One of the best features on this square is how quickly it handles repeat layout work. Instead of measuring and resetting for every line, you can use the built-in guides to keep your marks consistent along the edge of the material.
- Scribing guides are spaced on 1/16 inch centers
- Well suited for cabinet parts, panels, and repeat offset marking
Useful for Setup and Inspection
A good double square is not just for drawing lines. It is one of the handiest setup tools in the shop for checking machine settings, referencing off a table surface, and confirming that parts are where they should be before you make the cut.
- 6 inch blade size works well around router tables and smaller setups
- Laser-engraved scale is designed for readable, reliable reference work
Checks Assemblies Without the Fuss
Assembly checks are where a square like this saves headaches. You can get the head against the work, read the blade clearly, and spot small issues before they turn into bigger fit problems later in the build.
- Designed for assembly checks and close-in inspection work
- Compact square head gives solid reference on finished and machined parts

Pro Tip
When you are laying out a batch of identical parts, pick one scribing offset and run every piece before changing settings. That is where the 1/16 inch center guides save the most time and help keep your marks consistent from part to part.
