The Festool 201187 KA-UG-R-L Extensions for the Kapex, Imperial is an extension set built for the Festool Kapex system. This is a saw stand extension set designed for supporting long stock and setting repeat cuts on a Kapex miter saw station. Model number 201187. If you are working with trim, casing, molding, or other material that gets awkward once it passes the saw table, this setup gives you a cleaner, more controlled way to support the workpiece and measure it at the saw.

What matters here is not just added length, but usable length. Each side is designed to expand the support area for longer material, with the full setup supporting stock up to 94-1/2 inches to 95 inches depending on the source listing, and the extension arm length without telescope listed at 58 inches. In practical use, that means less sag at the ends of the board, less fighting the material during the cut, and better consistency when you are trying to hold tolerances across a stack of parts.

Festool also built real measuring and stop functionality into this set. The integrated imperial tape measure and adjustable stop are there for one reason: repeatability. Instead of marking every cut by hand, you can set the stop and run parts to length. That saves time on production trim work and reduces small measuring errors that tend to show up later during install.

The design is straightforward and jobsite-friendly. This kit includes both the left and right extensions, and they connect tool-free to the Kapex UG stand. That matters if you move between rooms, floors, or jobs and do not want to waste time bolting on support hardware every time you set up the saw station. The folding extension design also makes more sense for transport and storage than trying to manage separate roller stands and loose measuring accessories.

For users already invested in the Festool Kapex platform, this accessory makes the saw station more complete. It is suitable for the KS 120 and works with the Kapex UG stand, sold separately. There is also an important compatibility note: these UG extensions cannot be used with the older Kapex crown stops number 494369 that attach directly to the saw. If you need crown stop functionality with the UG extensions, Festool specifies crown stops number 203356 for that setup.

Who should buy this? Finish carpenters, trim crews, remodelers, cabinet installers, and serious shop users who want their miter saw station to do more than just hold the saw. If you are cutting short parts once in a while, this is probably more setup than you need. If you regularly cut long stock and care about repeatable lengths, the added support, built-in scale, and stop system make a real difference.
