The Festool Edge Guide OF 1400, model 492636, is a router edge guide made for the Festool OF 1400 router. This is a router edge guide designed for routing parallel to the edge of a workpiece. If you need clean, repeatable grooves, dados, flutes, ploughs, rabbets, or profiles without fighting freehand setup, this accessory is the part that makes the router behave in a much more controlled way.

What matters here is the adjustment. Festool gives this guide fine-adjustment control in 1/10 mm increments, which is the kind of feature that actually saves material when your cut location needs to be exact. Instead of nudging the setup by feel and hoping it lands where you want, you can dial in the distance from the material edge with much more confidence. For trim work, cabinet parts, joinery, and repeated edge-based routing, that level of control is a real advantage.

The guide is built from cast aluminum, so it is meant to hold its setting and stand up to regular shop and jobsite use. Festool also uses fiber-reinforced plastic thumbscrews for adjustment, which makes setup quicker without turning this into a fragile accessory. That mix of metal structure and easy hand adjustment is exactly what you want in a guide that gets installed, removed, and reset often.

Dust collection is another practical win. The integrated extraction hood helps remove chips while routing, which keeps the cut line more visible and cuts down cleanup after the work is done. On edge-routing tasks where debris can pile up fast, that matters just as much for accuracy as it does for shop cleanliness.

Compatibility is straightforward: this accessory is suitable for the Festool OF 1400 and attaches using integrated thumbscrews and the two steel rods that come with the router. That last part is important. This version is supplied without rods, so it is intended for users who already have the OF 1400 router and the guide rod setup that comes with that machine.

This accessory makes the most sense for woodworkers, cabinet installers, finish carpenters, and serious DIY users who want repeatable edge-referenced routing instead of improvised fences or shop-made guides. If you already run an OF 1400 and want faster setup, cleaner routing, and more dependable accuracy near an edge, the Festool Edge Guide OF 1400 is one of those accessories that earns its keep pretty quickly.
