Key Features
One-Hand ControlThe pump lever and built-in release let you clamp, adjust, and remove the Festool FS-EZ 150/2 One-Handed Clamp with one hand. That matters when your other hand is holding a guide rail, panel, or workpiece in position. Clamp or SpreadTool-free conversion lets the same clamp handle standard clamping, overlap clamping, and spreading. Instead of reaching for different accessories, you can reconfigure it fast and keep moving. Built for Festool RailsThis one-handed clamp is made to fit the clamping grooves on Festool guide rails, MFT 3, and the MW 1000 Mobile Workshop. It gives you a secure hold for guided cutting, positioning, and table work without fighting setup.
Overview
The Festool FS-EZ 150/2 One-Handed Clamp, model 578623, is a compact clamping accessory made for securing Festool guide rails, workpieces, and MFT table setups with less fuss. This is a one-handed clamp designed for fastening guide rails, holding workpieces, and spreading material when needed. If you use Festool rails for track saw work, cross cutting, or repeatable layout on an MFT table, this clamp gives you a faster way to lock things down without tying up both hands.
What makes this clamp useful is not just the 6 inch clamping width. It is the fact that it can also switch over to spreading, with a spreading range from 4-3/4 inches to 12-3/16 inches. That means the same accessory can hold a rail in place for cutting sheet goods, secure a part on the table, or push material apart during fitting and assembly. For a small accessory, that kind of range makes it a legitimate everyday shop and jobsite piece rather than a one-task add-on.
The one-handed pump action is the real selling point here. When you are setting a guide rail on plywood or trying to keep a workpiece aligned on an MFT top, having one hand free matters. Festool built in an ergonomic pump lever along with an integrated release lever, so clamping and repositioning are quick from either direction. In plain terms, you can hold the material where you want it and still get the clamp engaged without asking for a second set of hands.
Festool also gave the FS-EZ 150/2 a tool-free conversion setup. You can reposition the jaw to go from clamping to spreading without digging around for extra hardware or wasting time in the middle of a setup. It also supports overlap clamping, which adds flexibility when you need to secure material in less straightforward positions. That is the kind of detail that makes sense for cabinet work, trim fitting, and track saw cutting where setups change constantly.
On the contact points, the plastic protective cap is there for a reason. It helps keep the hold from slipping while being gentler on finished surfaces and workpieces you do not want chewed up by bare clamp faces. That makes this clamp a better fit for finished panels, veneered stock, laminate, and other materials where damage at the clamp point creates cleanup work later.
System compatibility is a big part of the value. The clamp is suitable for the clamping groove of all Festool guide rails, including FS/2, FS/2-KP, and FSK, and it also works with the MFT 3 and MW 1000 Mobile Workshop. If your workflow already revolves around the Festool guide rail system, this is one of those accessories that helps the whole setup work the way it is supposed to. It is not a generic trigger clamp trying to do rail duty. It is made for the slots and grooves you are actually using.
Because this is sold as a 2-pack, you can secure both ends of a rail or keep two hold points on a workpiece without buying duplicates later. For guided cutting, that is the practical advantage. One clamp is better than none, but two clamps are what give you stable, repeatable positioning when accuracy matters.
Who should buy it? Woodworkers, cabinet installers, finish carpenters, remodelers, and serious DIY users already using Festool guide rails or an MFT table will get the most from it. If you do not own the Festool rail and table system, it is still a capable clamp and spreader, but the real reason to buy the Festool FS-EZ 150/2 One-Handed Clamp is how cleanly it integrates into that system for controlled cutting, clamping, and setup work.
Secure Your Guide Rail Faster
When you are setting up for guided cutting, the clamp should help the job, not slow it down. This setup shows exactly where the FS-EZ 150/2 earns its keep: holding the rail where you want it while you keep moving.
- One-handed operation helps when the other hand is positioning the rail or material
- Designed for secure clamping and positioning of FS/2, FS/2-KP, and FSK guide rails
Fits the Festool Table System the Right Way
This clamp is made to work in the side groove of the MFT 3 and Mobile Workshop, which means less improvising and a more stable setup. For layout, trimming, and repeat work, that gives you better control from the start.
- Compatible with MFT 3 and MW 1000 Mobile Workshop clamping grooves
- Useful for securing workpieces directly on the table during assembly, trimming, or guided cuts
More Than Just a Rail Clamp
The FS-EZ 150/2 is more flexible than a basic trigger clamp. Tool-free conversion lets you switch between clamping, overlap clamping, and spreading, so the same pair can cover setup jobs that usually need more than one type of clamp.
- Clamping width up to 6 in. (150 mm)
- Spreading width from 4-3/4 in. to 12-3/16 in. (120 to 310 mm)
Compact Design, Everyday Use
Compact clamps tend to become the ones you grab all the time, especially when they are fast and do not beat up the work. The protective cap and ergonomic handle make this a better choice for finished material and repeated setups.
- Plastic protective cap helps prevent slipping and reduces marring on the workpiece
- Ergonomic pump lever with integrated release lever allows quick adjustment and removal

Pro Tip
If you are clamping a guide rail for sheet goods, use both clamps as a pair instead of relying on one end. You will get a more stable rail, especially on longer cuts, and spend less time checking whether the rail shifted during setup.

Festool FS-EZ 150/2 One-Handed Clamp That Actually Makes the System Better
If you already work off Festool rails or an MFT table, this is one of those accessories that feels optional until you use it, then it stays in the setup full time.
- Who it’s for: Woodworkers, cabinet guys, trim carpenters, and serious DIY users who want faster guide rail fastening and cleaner MFT workholding.
- Why it stands out: The one-handed action is genuinely useful, and the clamp-to-spreader conversion gives this pair more range than a basic rail clamp.
- Worth knowing: The real value is system fit. If you own Festool rails, MFT 3, or the mobile workshop, you will get more out of it than someone looking for a generic shop clamp.
