These extension wings provide stable left- and right-hand support to keep workpieces flat and aligned, resulting in cleaner, more consistent cuts, especially when working with long or delicate profiles like crown and baseboard. The tool-free mounting system allows quick attachment to the KAPEX saw base or underframe using Festool’s V-groove interface. Each wing features a telescoping extension with an integrated dual-scale measuring system in both imperial and metric units, along with adjustable flip stops for fast, repeatable length cuts, enabling you to confidently cut multiple pieces to the same length with efficiency.\n\nBuilt for both jobsite and shop use, the extension wings fold and retract quickly for compact transport and storage. Whether used with the underframe as a complete cutting station or independently, these extensions transform your KAPEX into a precise, repeatable length-cutting solution ideal for professional trim and finish work. The system supports long boards, beams, and square stock up to approximately 8 feet (2.40 m) and offers flexible setup options, including folding support legs that allow placement directly on the ground to maintain consistent working height.\n\nModel Number: 578921","brand":"Festool","offers":[{"title":"Default Title","offer_id":47963693088931,"sku":"1995296","price":699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/2469\/7763\/files\/ecfd50a4172c951a275c866d508f8be7bf9f5efc_1995296_1.png?v=1786089488","url":"https:\/\/www.hartvillehardware.com\/products\/festool-578921-extension-set-ka-ug-ks-120-r-l-d","provider":"Hartville Hardware","version":"1.0","type":"link"}
