What this tool adds
What this tool adds to your bench
This DFM tool combines a small right-angle square with a center-finding arrangement. The two supplied pins register on opposite sides of the work while the center opening provides a pencil position. Choose it when you want those functions in a compact tool rather than a full-size layout square.
The illustrated body is 2-5/8 inches tall and 1-5/8 inches wide, with 5/8 inch-wide legs. Compare that short reference length with the part you need to check. A small square can be convenient around a joint, but its dimensions do not establish the same reach as a longer square.
The selected version is blue aluminum, supplied with two center-finding pins. The listing describes the center marking opening at approximately 0.34 inch. Compare your pencil with that opening rather than expecting every pencil shape to fit equally well.
Choose the Woodpeckers MT Center Gauge instead when interchangeable joint-width bars and a two-inch stock-thickness capacity are the relevant functions. This DFM selection offers a smaller square-and-pins format; its maximum center-finding stock width and a verified accuracy tolerance are not established here.

Questions before you choose
When is the compact size useful?
Compare it for small parts and local right-angle references where a short square can register. Choose a longer square when the work needs a longer reference edge.
Are the center-finding pins included?
The selected contents field names two pins, matching the two loose pins pictured with the blue square.
Should I choose this or the MT Center Gauge?
Compare this for its compact square-and-pins format. The MT Center Gauge adds interchangeable joint-width bars and an established stock-thickness capacity, which may matter for centered mortise and tenon layout.
