The Festool 492601 Guide Stop OF 1400 is a router accessory built to adapt the Festool OF 1400 router for use with the FS Guide Rail System. This is a router guide stop designed for straight routing with better control and repeatable accuracy. Model Number: 492601.

What makes this accessory matter is simple: it gives the OF 1400 a guided path for grooves, dados, edge routing, and other straight-line work where drifting even a little can ruin the result. The fine-adjustment control lets you set the cutting distance in 1/10 mm increments, which is the kind of adjustment that saves time when you are sneaking up on a final fit instead of recutting material.

The design is built around practical use, not extra complexity. It attaches quickly using the two rods that come with the OF 1400 router, and the knobs double as handles while guiding the router along the rail. Festool also includes a support foot that helps level the router to the guide rail surface, which improves stability and keeps the pass smooth.

For shop work and finish work, that extra support is a bigger deal than it sounds. A router that stays level on the rail is easier to control, especially when you are making long passes in sheet goods or trimming with a consistent offset. Instead of fighting the setup, you can focus on feed rate, bit selection, and cut quality.

Compatibility is straightforward. This guide stop is made for the Festool OF 1400 and is intended for use with Festool FS Guide Rails. It does not include the rods, because those come with the OF 1400 router itself.

If you already own an OF 1400 and want more precise guided routing without moving to a dedicated jig for every task, this is the right add-on. It makes the most sense for cabinet work, built-ins, trim, furniture work, and any job where straight, repeatable routing matters more than improvising your setup.
