The Festool KA-UG-KS 60 R/L/D Extension Set (578920) is a left and right miter saw extension wing system designed to provide edge-aligned material support for Festool KAPEX KS 60 and KSC 60 miter saws. Used in conjunction with the UG-KAPEX KS 60 Adapter Base, this folding extension set expands the support surface from 58.26 in. (1,480 mm) up to 94.48 in. (2,400 mm) to keep long boards, beams, trim, and profiled molding stable and level during precision length cutting on jobsites or in the shop.

Designed for rapid deployment and efficient workflow, the extension wings attach tool-free directly to the saw via Festool's V-groove mounting interface. Integrated telescoping slide-out scales and adjustable flip stops allow finish carpenters and trim specialists to set and repeat precise cut lengths with confidence. Fold-out support legs adjust to match working height for added stability under heavy stock, while the entire assembly folds down compactly for transport between job locations.

Features & Benefits

• Extended Stock Support: Expands from 58.26 in. (1,480 mm) to 94.48 in. (2,400 mm) to support workpieces up to approximately 8 ft. (2.40 m) for cleaner, safer cuts.
