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
- Non-marring plastic foot helps protect finished surfaces
- Rated for workpieces up to 4-3/4 in. high

Pro Tip
When you are cutting finished trim on the KS 120, set the clamp as close to the fence as the stock allows. That gives the workpiece better support right where movement usually starts and helps the non-marring foot do its job without leaving marks.

Tool Nut's Take
Festool 494391 Kapex Miter Saw Replacement Hold Down Clamp Is a Small Add-On That Fixes a Big Annoyance
If you own a KS 120 and want stock to stay put without beating up finished material, this clamp earns its spot fast.
- Who it's for: KAPEX users doing trim, casing, molding, and other precision miter saw work where movement at the cut line costs time and accuracy.
- Why it stands out: The cam-action setup is quick, the foot is built to protect the material, and the shape works well near the fence where a lot of clamps get awkward.
- Worth knowing: This is a KS 120-specific accessory and includes one clamp, so it is the right buy for a replacement or for matching the original setup, not a universal miter saw clamp.
