The Swan Firehawk Trim Square and Falcon Depth Stop Combo Kit (SS375) is a compact layout and setup tool built for trim carpenters, cabinet installers, woodworkers, and anyone who needs quick, repeatable measurements at the bench or on site. This is a carpentry square designed for layout, joinery, and machine setup work. Model Number: SS375. Instead of carrying a small square and a separate depth gauge, this setup combines both functions into one tool that handles marking, reveal spacing, and depth settings with less guesswork.

What makes this tool matter is the FALCON Depth Stop system. The fence is designed so the depth stop can remain attached without getting in the way during regular square use. In real use, that means you can move from laying out trim to setting blade depth on a table saw, router, or bandsaw without swapping tools or resetting from scratch. If you do a lot of repeat cuts, stopped dados, trim work, or machine setup, that kind of speed adds up fast.

The FIREHAWK layout square is also built to be easy to read. Swan uses high-visibility laser etching on both sides of the fence and on the back, which gives you more layout references and helps when you are transferring settings from one operation to the next. That matters on small parts and trim stock where a fuzzy mark or hard-to-read scale can throw the whole piece off. The 3.75-inch size keeps it nimble for tighter work, especially where a full-size square feels clumsy.

For marking, the precision-machined slanted fence is one of the better details here. It is not just a design choice. A slanted edge gives you a cleaner registration point for pencils and marking knives, so your line lands where you want it instead of wandering along a thick edge. That is useful for hardwood layout, miter work, and fine trim where a line that is off by even a little bit turns into a fit problem later.

Swan also built reveal offsets right into the tool, including 1/8 inch and 1/4 inch offsets. If you install trim, face frames, or cabinetry, that saves time because you are not stacking scraps, hunting for spacers, or eyeballing reveal lines. Integrated offsets are one of those features that seems small until you use it every day. Then you start wondering why more trim squares do not include them.

Construction is another strong point. The SS375 is made from durable anodized aluminum, which gives it the stiffness and wear resistance you want in a square that will see regular handling, tool bags, benches, and machine tables. It is built for real shop and jobsite conditions while still keeping the compact footprint that makes it easy to carry. The anodized body also helps the markings stay readable and the tool stay dimensionally consistent over time.

In terms of compatibility, this square is designed to work across common woodworking and carpentry tasks. Swan specifically calls out use for saws, routers, and bandsaws when setting depth. It also works with most carbon pencils for layout marking, which is a practical detail for guys who already have a preferred marking tool and do not want to buy a special pencil just to use a square properly.

If you are a finish carpenter, cabinetmaker, furniture builder, or serious DIYer who cares about clean layout and repeatable settings, this tool makes a lot of sense. It is especially useful for users who move between marking stock and dialing in machine cuts throughout the day. If all you need is a basic square to strike an occasional 90-degree line, this may be more tool than you need. But if you actually use your square as a setup tool, not just a marker guide, the SS375 earns its space fast.

Swan Firehawk Trim Square and Falcon Depth Stop Combo Kit (SS375) is a smart buy for guys who actually use a square all day
