Ironbark Dovetail Attachment for 90° Try Squares

The Ironbark Dovetail Attachment transforms your standard 90° try square into a precise dovetail layout tool, allowing you to accurately mark 1:6 or 1:8 dovetail angles with confidence and repeatability.

Machined from solid brass, the attachment screws directly into compatible 3″ or 5″ Ironbark 90° try squares, providing a rigid, stable reference for consistent dovetail layout. The attachment is secured with an M3 hex-head screw, making it quick to install, remove, or switch between ratios as needed.

Designed for precision and durability, the brass construction resists wear while offering excellent tactile feedback during layout. When removed, your try square returns to standard 90° use with no permanent modification.

Note: This product includes the dovetail attachment only. The required 90° try square is not included.
