Festool Overhead Boom Arm for Dust Extractors, CT-ASA FLX J (578517)
Festool Overhead Boom Arm for Dust Extractors, CT-ASA FLX J (578517)
Key Features
Overview
The Festool CT-ASA FLX J Overhead Boom Arm for Dust Extractors (578517) is a hose and cord management accessory designed for anyone running a Festool CT dust extractor who's fought with a suction hose dragging across a bench, catching on a workpiece, or getting stepped on mid-cut. This is an overhead boom arm accessory built to route a dust extractor's hose and power cord above the work area instead of across it. It mounts to the extractor via T-LOC and swivels for extra clearance, letting you move freely around the tool without the hose fighting you for space.
The arm itself is built from modular, lightweight chain links, which is what makes it adjustable rather than a fixed-length rod. If the full reach is more than your setup needs, you pull links out and shorten it; if you need more room, you add them back. A telescoping tube measuring 24.8 in. (630mm) handles the height side of the equation, letting you dial in exactly how high the arm sits above your bench or workstation. Hose and power cord route along the arm and secure to the chain links with hook-and-loop straps, so nothing dangles loose or swings into your line of sight while you work.
A "plug it" cable system is built into the design specifically so you can swap tools quickly without disconnecting or rerouting the whole setup — useful if you're moving between a sander, a track saw, and a router on the same dust extractor over the course of a job. The SYS-MFT Systainer that houses the arm isn't just a storage case, either: its lid has an MFT-style perforated top, so it doubles as a surface for clamping and workholding once it's unpacked.
On the practicality side, this is an accessory built around actually breaking down and moving. The chain-link construction lets the whole arm collapse and store inside the SYS-MFT Systainer for transport, and setup on site is fast — mount it to the dust extractor, extend the telescoping tube to height, and route your hose and cord along the arm.
Compatibility is straightforward: this boom arm is built for Festool CT 26 through CT 48 dust extractors, and it also mounts to Festool MFT multifunction tables and the MW 1000 mobile workshop, so it fits into a stationary bench setup or a jobsite cart equally well.
Buy this if you run a CT dust extractor at a semi-permanent station — a shop bench, an MFT table, or a mobile workshop cart — and you're tired of managing a loose hose every time you switch tools. It's a strong fit for woodworkers, cabinet installers, and finish carpenters doing repeated sanding, sawing, or routing at one location. If your dust extractor moves from room to room on every job with no fixed station, the setup and breakdown time may not pay off compared to just managing the hose by hand.

Pro Tip
The chain links are modular for a reason — if the full 3.28-ft reach puts the arm swinging into your peripheral vision at a smaller bench, pull a few links out to shorten it. Less arm in the way means less distraction while you're sanding or routing.
Tool Nut's Take
Get the Hose Off Your Bench for Good
The Festool CT-ASA FLX J Overhead Boom Arm solves a problem most CT dust extractor owners just live with — a hose that's always in the way — by lifting it overhead and out of the workspace entirely.
- Who it's for: Woodworkers and cabinet shops running a CT dust extractor at a fixed bench, MFT table, or mobile workshop cart who want the hose and cord out of the work area for good.
- Why it stands out: The combination of a swiveling, adjustable-length arm and a Systainer that packs down for transport means it's as much at home in a permanent shop station as it is on a jobsite cart.
- Worth knowing: This is an accessory, not a standalone product — you'll need a compatible Festool CT 26 to CT 48 dust extractor already on hand, since one isn't included.
Common Questions
- Which dust extractors does this fit? Festool CT 26 through CT 48 dust extractors, using a T-LOC mounting connection.
- Does this work with an MFT table? Yes — it also mounts to Festool MFT multifunction tables and the MW 1000 mobile workshop.
- Can I adjust the length of the arm? Yes. The arm's chain links are modular, so you can remove links to shorten the roughly 3.28-ft (1 m) reach to fit your setup.
- Is the dust extractor included? No. This is an accessory for an existing Festool CT 26 to CT 48 dust extractor, which is sold separately.
