Festool FS-WA/90 90 Degree Guide Rail Edge Square

The Festool FS-WA/90 is a 90-degree guide rail edge square designed to deliver accurate, repeatable perpendicular cuts when used in conjunction with a Festool guide rail system.

Machined from a single piece of aluminium using a CNC process, the angle stop provides a consistently true 90° reference — eliminating the need for readjustments between cuts. This makes it particularly well suited to carpenters, joiners, and site carpenters who need reliable square cuts across sheet materials without time-consuming setup.

The quick-change system allows the stop to attach to the guide rail rapidly and aligns itself automatically, reducing preparation time on site. The long contact edge makes alignment straightforward against any workpiece, while grooves on both the front and rear allow guide rail clamps to be secured in position.

When combined with a portable circular saw, saw table, or work bench, the FS-WA/90 effectively converts your guide rail setup into a mobile panel saw — ideal for cutting sheet goods such as plywood, MDF, and laminate board accurately in the field or workshop.
