FS guide rail rapid clamp is a Festool clamp set designed to position and clamp Festool FS guide rails to sheet good material, so the rail stays fixed while you cut or rout. The clamp mounts to the Festool FS guide rail using the continuous bottom t-slot, creating a sliding connection that follows the rail length. That continuous t-slot mounting gives limitless adjustability along the guide rail, so you can set clamping pressure exactly where the work needs support. The FS rapid clamp works on all types of sheet good material, so the same clamp handles plywood, MDF, or other panel stock in the shop. One-handed trigger action operates the clamp, allowing you to hold the guide rail to the sheet edge with one hand while tightening with the other, which streamlines setup on the material edge.
This Festool FS guide rail rapid clamp mounts directly into the continuous bottom t-slot along the FS guide rail, so sliding the clamp into position becomes part of the setup. Because the t-slot connection is continuous, the clamp can be positioned at any point along the rail, which supports edge clamping on long or short cuts. The one-handed trigger action tightens the jaws against the sheet good material, so installers can hold the rail to the panel edge and lock it using a single-hand squeeze. As the jaws grip the sheet material, the FS guide rail stays pressed to the surface, helping maintain the rail line throughout the cut. Designed for all types of sheet good material, this mounting and adjustment approach suits a range of panel jobs.
The FS rapid clamp and fixed jaws for guide rail system are part of Festool woodworking tools and equipment, specifically in the hand tools clamp class, so they integrate naturally into clamping tasks around guide rail cutting. When this clamp is mounted into the continuous bottom t-slot of a Festool FS guide rail, it runs along the rail underside, locating its holding force directly under the rail body. That mounting position keeps clamping pressure close to the cutting path on all types of sheet good material, which helps stabilize the rail during cuts. Since the clamp fits all Festool guide rails, the same setup applies whether the rail spans a small cabinet panel or a full sheet good, which keeps the clamping approach consistent across different panel sizes. In a woodworking environment supplied by Wurth Baer Supply, this clamp operates as a job-focused tool within broader Festool and clamping workflows.
The continuous bottom t-slot connection on the FS guide rail rapid clamp is significant because limitless adjustability allows the jaws to be placed where clamping force best supports the rail, helping reduce rail movement in the middle or at the ends of a cut. When one-handed trigger action is used to tighten the clamp on the material edge, the installer can hold the guide rail flush to the sheet side while engaging the clamp, which supports repeatable rail positioning during repetitive panel cuts. The fixed jaws aspect of this set means the clamping faces stay aligned as pressure is applied, which helps grip sheet good material squarely without shifting the rail sideways. Because the clamp is designed for rapid positioning on Festool FS guide rails, users can reposition it quickly between cuts, which supports a workflow of frequent rail movements across multiple sheet good pieces.
The FS guide rail rapid clamp positions and clamps Festool FS guide rails to sheet good material, so the rail remains held to the panel surface while cutting or routing along the guide.
The clamp mounts to Festool FS guide rails using the continuous bottom t-slot, so it slides into the slot and can be moved anywhere along the guide rail length before tightening.
Limitless adjustability from the continuous t-slot allows positioning the clamp exactly where support is required, helping apply holding force at critical points along the rail span.
The one-handed trigger action lets the user tighten the clamp while holding the guide rail against the sheet edge, which speeds setup and supports consistent rail alignment.
This Festool clamp fits all Festool guide rails, so one FS rapid clamp and fixed jaws set can serve across different rail sizes in the same guide rail system.
The 489790 part number identifies the FS rapid clamp and fixed jaws for the Festool FS guide rail system, helping match the clamp set to the correct Festool rail family.
The FS guide rail rapid clamp and fixed jaws from Festool provides rapid positioning and clamping of Festool FS guide rails to all types of sheet good material, using a continuous bottom t-slot mount and one-handed trigger action. For shops sourcing through Wurth Baer Supply, this clamp integrates into existing Festool FS guide rail systems, supporting guide rail cuts where the rail needs to stay aligned on panels. Choosing this clamp lets users apply limitless adjustability along the rail while working within a familiar Festool part numbering system.
