FESTOOL Extension Set KA-UG-KS 120 R/L/D

Built for precise, repeatable length cuts.

The extension wings expand the support surface of your Festool KAPEX miter saw, making it easier to handle long stock such as trim, molding, and framing material with accuracy and control. By providing stable left- and right-hand support, they help keep workpieces flat and aligned for cleaner, more consistent cuts—especially when cutting long or delicate profiles like crown and baseboard. Tool-free mounting allows the wings to attach directly to the KAPEX saw base or underframe in seconds using Festool’s V-groove interface. Each wing features a telescoping extension with an integrated dual-scale measuring system (imperial and metric), along with adjustable flip stops for fast, repeatable length cuts. Once set, you can cut multiple pieces to the same length with confidence and efficiency. Designed for both jobsite and shop use, the extension wings fold and retract quickly for transport, keeping the system compact and easy to move between locations. Whether paired with the underframe as a complete cutting station or used independently, these extensions turn your KAPEX into a precise, repeatable length-cutting solution for professional trim and finish work.

Key Benefits

• Built for portability: Folds down compactly for safe, space-efficient transport and storage.
• Accurate, repeatable cuts: Integrated measuring scale and adjustable flip stop make it easy to dial in precise, repeatable lengths.
• Extended material support: Telescoping slide-out scale supports long workpieces up to approximately 8 ft (2.40 m).
• Flexible setup options: When using the KAPEX without the underframe, the support legs fold back so the extensions can be placed directly on the ground—keeping the saw and support surface at the same working height.
