Key Features
Fast Cam LockThe cam-action design clamps stock quickly without fussing with a slow screw mechanism. That means faster setup and better workpiece control at the saw. Protects Finished StockA non-marring plastic foot helps hold material securely without chewing up trim, painted parts, or prefinished boards during cutting. Kapex-Specific Hold DownThe Festool 494391 Kapex Miter Saw Replacement Hold Down Clamp is built for the KS 120 and can be positioned to the left or right of the blade for more flexible cutting support.
Overview
The Festool 494391 Kapex Miter Saw Replacement Hold Down Clamp is a replacement workpiece clamp made for the Festool KS 120 KAPEX miter saw. This is a hold down clamp designed for securing workpieces during miter saw cutting. Model Number 494391. If you want cleaner, safer cuts on trim, molding, or other stock that tends to shift on the saw deck, this accessory solves a real problem fast.
The big selling point here is the fast-action cam design. Instead of wasting time cranking down a traditional clamp, you can lock material in place quickly and move on to the cut. That matters when you are repeating the same cut over and over, or when you are trying to keep narrow or awkward stock from lifting or drifting as the blade comes down.
Festool also got the contact point right. The non-marring plastic foot helps protect the face of the material, which is especially useful when you are cutting painted trim, prefinished casing, or visible finish pieces you do not want to touch up later. The octagonal foot shape also helps the clamp sit securely close to the fence, where good support matters most.
This clamp can be used on either the left or right side of the blade, giving you more flexibility depending on your setup and the length of the stock. Festool rates it for workpieces up to 4-3/4 inches high, which covers a wide range of common miter saw tasks. For KS 120 owners who need a replacement or want the same hold-down performance as the original clamp, this is the correct accessory.
Who should buy it? KS 120 users cutting finish materials, installers doing repeat cuts, and anyone who wants better workpiece control on a KAPEX. It is a simple accessory, but it makes a noticeable difference when accuracy, material protection, and safer cutting are the goal.
Better Control at the Cut Line
This clamp is about keeping the workpiece planted where you put it. On a miter saw, that means more consistent cuts, less stock movement, and less chance of marking up finish material while you work.
- Fast-action cam design speeds up clamping and repositioning
- Works on the left or right side of the blade for flexible setup
