This is a miter saw extension accessory built for anyone cutting long material — trim carpenters, finish crews, and cabinet shops — who need a workpiece to stay flat and supported instead of see-sawing off the ends of a standard saw table. It replaces two older item numbers, 201187 and 497514, and consolidates them into a single set: the previous imperial-only wing (201187) and the previous metric-only wing (497514) are gone, replaced here by one dual-scale set that reads both imperial and metric measurements on the same telescoping arm.\u003c\/p\u003e\n\u003cp\u003eEach wing — a left extension (497353) and a right extension (497352) — telescopes out from 58-1\/4-in to 94-1\/2-in (1480mm to 2400mm), which is the difference between fighting a piece of crown molding that overhangs the saw table and having it fully supported from end to end. An adjustable flip stop lets you set a length once and cut multiple pieces to that exact same length without re-measuring for every cut — set it, flip it down, make the cut, flip it back up out of the way for the next piece that needs a different length, then flip it back down when you return to the repeat cut.\u003c\/p\u003e\n\u003cp\u003eThe mounting system is what makes this practical for everyday use rather than a one-time setup: both wings attach to the KAPEX KS 120 saw base or to the optional underframe using Festool's tool-free V-groove interface, so there's no wrench work involved in breaking the station down or setting it back up. When the underframe isn't in play, the support legs on each wing fold back so the extensions sit directly on the ground at the same working height as the saw — useful for jobsite setups where a full underframe station isn't practical to haul in and out.\u003c\/p\u003e\n\u003cp\u003eThis set is built specifically for the KAPEX KS 120 and doesn't function as a generic material support — it's a dedicated accessory for that saw's base and underframe geometry. For anyone running a KAPEX KS 120 who regularly cuts baseboard, casing, crown molding, or long framing and square stock, this set turns a saw with a small stock table into a real length-cutting station capable of handling material up to nearly eight feet long, with the accuracy of a built-in measuring system instead of a tape measure and a pencil mark.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\u003csummary\u003e\u003ch2\u003eSet Up Once, Cut Repeatably\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/50174971937062_d2597aa72019.jpg\" alt=\"Festool Extension Wing Set for Kapex KS 120 left and right extension arms with support legs and adjustable flip stop supporting long trim and board stock on a miter saw station\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eLong stock only cuts clean when it's fully supported — otherwise the far end drops as you cut, the piece pivots, and the cut comes out with a taper.
