Festool Extension Wing Set for Kapex KSC 60 Miter Saw (578920)

The Festool Extension Wing Set for the Kapex KSC 60 Miter Saw adds material support on both the left and right sides of the saw, built for carpenters and installers who cut long trim, molding, and framing stock and need it to stay flat and aligned through the cut. This is a miter saw support accessory designed for length-cutting accuracy on long workpieces. This set succeeds Festool item number 201909 — it's the same left-and-right extension wing design, tool-free V-groove mounting, telescoping scale, and folding legs, reissued under a new item number. There are no functional changes from the previous version.

Each wing telescopes from a retracted length of 58-1/4-in (1480mm) out to a maximum support length of 94-1/2-in (2400mm), which means a single set gives you close to 8 feet of supported stock per side once both wings are extended. On a long piece of crown or baseboard, that's the difference between a clean cut and a piece that sags and binds the blade as it drops.

The flip stop and the telescoping slide-out scale — supplied in imperial units — work together for repeat cuts. Set the stop once against your target length and every subsequent piece registers against it automatically, so you're not re-measuring and re-marking a stack of identical trim pieces one at a time.

Mounting is tool-free through Festool's V-groove interface, so the wings attach directly to the KSC 60 on their own for quick setup, and they're also designed to work in conjunction with the separate UG-KAPEX KS 60 underframe for elevated, freestanding support when you need the saw and both wings working as one stable station. The support legs fold out for a stable working height and fold flat again when the job's done, so the wings collapse down for transport rather than staying rigged out at full length.

This extension set is built for trim carpenters, cabinet installers, and framing crews running the Kapex KSC 60 who regularly cut long stock and need consistent, repeatable lengths without babysitting a tape measure on every piece. If you're already running a KSC 60 and cutting anything longer than a couple feet, this is the accessory that turns it into a real length-cutting station.

Turns the Kapex Into a Real Length-Cutting Station

The Festool Extension Wing Set for the Kapex KSC 60 is what keeps long trim stock flat, aligned, and cut to a consistent length.

• Who it's for: Trim carpenters and installers running the KSC 60 who cut long casing, baseboard, or rail stock and need it supported on both sides.
• Why it stands out: Nearly 8 feet of support per side, tool-free mounting, and a flip stop that eliminates re-measuring — this is a repeatable-cut setup, not just a folding shelf.
• Worth knowing: This replaces item number 201909 with no functional changes — same wings, same mounting, new part number. If you already own 201909, there's nothing new here to upgrade for.

• Will this fit my Festool Kapex KSC 60? Yes, it's built specifically for the KSC 60's V-groove mounting interface.
• Do I need the underframe to use these wings? No. They mount directly to the saw on their own, and also work in combination with the separate UG-KAPEX KS 60 underframe for elevated, freestanding support.
• How long is the material support once extended? Each wing telescopes out to 94-1/2-in (2400mm), giving close to 8 feet of support per side.
• What did this replace? This set succeeds item number 201909 with the same design and no functional changes, just reissued under a new item number.
