The Festool 493233 Table Widener OF 1400 is a router base accessory made for the Festool OF 1400 router. This is a router accessory designed for edge routing with better support, larger bit clearance, and improved dust collection. Model Number: 493233. If you use an OF 1400 for detail work along edges or need to run larger profile bits, this add-on gives the router a wider, more stable footprint where it matters most.

The big reason this accessory matters is simple: routing near an edge gets less forgiving as the base loses support. The oversized, heavy-duty base plate increases the contact area on the workpiece, which helps the router stay planted instead of tipping or rocking. In real use, that means smoother starts, steadier finishes, and less chance of wasting material on narrow edges or tricky profiles.

Festool also opened up the center aperture to a maximum of 2-1/2 inches. That larger opening expands what the OF 1400 can do by allowing the use of larger bits that would be limited by the standard base setup. If your work includes more substantial edge-forming profiles, this accessory makes the router more capable without changing the core tool.

Dust control is built into the design as well. The integrated rotating chip catcher improves extraction during use, which helps keep chips moving away from the cut area. That is useful not just for cleanup, but for visibility when you are trying to stay consistent on an exposed edge. Festool also notes integrated magnets that hold the dust collector securely in position, so the setup stays where you want it while you work.

From a design standpoint, this is not just a bigger plate. It is built as a running pad with support extension and chip deflector, with very good sliding properties for smooth movement across the work surface. That matters on finished stock, long edge passes, and any situation where a sticky or uneven base would show up in the cut.

Compatibility is straightforward: this accessory is made for the Festool OF 1400, including OF 1400 EQ fitment called out in supplemental product data. It is a purpose-built router accessory, not a universal base, so it makes the most sense for users already invested in the OF 1400 platform and looking to get more out of that router.

If you are a cabinet installer, finish carpenter, trim worker, furniture builder, or serious DIY woodworker using an OF 1400, this is the kind of accessory that solves a real routing problem. It is especially useful for precise edge routing, larger decorative profiles, and any work where base support at the edge can make or break the result.
