Festool Crown Stops AB-KA-UG/2 is a crown stop accessory set for Festool Kapex miter saw setups. This is a crown stop designed for positioning crown molding at an angle during trim work. Model Number: 203356. It is made for users who already run a Festool KS 120 or KSC 60 with the KA-UG trimming attachment underframe and want better support when cutting nested crown.

What matters here is not just that these are stops, but what kind of work they clean up. Crown molding is awkward to hold consistently because the stock sits at an angle and wants to roll or shift if the support is not right. The Festool Crown Stops AB-KA-UG/2 support nested workpieces at any angle, which helps keep the molding positioned the way you intended before the blade comes down. That is the difference between repeatable trim cuts and chasing fit-up around the room.

Festool also built these to add support on either side of the saw. On a miter saw station, that matters when you are feeding longer pieces of molding and need the stock to stay stable before and after the cut. Better side support means less chance of the profile dipping, twisting, or pulling away from your reference point. If you do finish carpentry, that stability is worth more than it sounds on paper.

Another practical advantage is the T-groove functionality. Additional stops and fastening clamps can be secured in the T-groove, which gives you more flexibility if your setup changes from one trim job to the next. That makes this accessory more than a one-trick add-on. It fits into a more modular cutting station for crown, trim, and other angle-sensitive stock.

Compatibility is the key buying point, so it is worth being direct about it. These crown stops are only compatible with the KA-UG trimming attachment underframe, sold separately. They are suitable for the KS 120 and KSC 60. If you do not have the KA-UG setup, this is not the accessory to buy. If you do, it is one of the cleaner ways to make your Kapex station more useful for crown molding and finish work.

The set includes two crown stops, which is the right way to package this kind of accessory because trim work usually benefits from support on either side of the saw depending on cut direction, stock length, and station layout. For carpenters, remodelers, and finish crews dialing in a Festool miter saw station, this is a practical upgrade that helps the saw handle crown molding the way it should have from the start.
