Key Features
Overview
The Festool CT-ASA FLX W Overhead Boom Arm, Wall-Mount (item number 578518) is a permanent, wall-mounted extraction arm built to manage hose and cord in a workshop or shop-based work cell. This is an overhead hose and cord management accessory designed for keeping the area around a stationary workstation clear while you sand, saw, or route. It's built for woodworkers, cabinet shops, and any workshop running a Festool dust extractor at a fixed bench or tool station, where the same hose and cord get dragged across the floor dozens of times a day.
The arm is built from 13 lightweight, modular plastic chain links that route the hose and cord overhead instead of along the floor, and hook-and-loop straps secure both to the links so they stay bundled and controlled rather than swinging loose. Extended out, the arm reaches nearly 5 ft. (1.5 m) — plenty of overhead coverage for a bench, table saw outfeed, or sanding station — and because the links are modular, you can remove a few to shorten the reach if your ceiling height or bench layout calls for less. A telescoping tube lets you fine-tune the height, and the whole arm swivels, so when you're not actively extracting you can rotate it out of the way instead of working around a hose hanging in your line of sight.
Installation is a wall bracket, included with the arm, that's designed to mount to most common wall types for a stable, permanent setup — this isn't a clamp-on accessory you fuss with each time, it's meant to live on the wall next to your dust extractor and stay there. Once mounted, it becomes a fixed point that keeps your extraction hose and cord organized and predictable, run after run, which matters more than it sounds like once you've caught a hose on a workpiece corner one too many times.
On the system side, the boom arm is built around Festool's CT dust extractors and is sized for the CT 26 through CT 48 lineup, and it plays well with accessories like the CT CYCLONE pre-separator when you're running high-volume sanding or sawing dust. If your extractor also uses Festool's plug-it cord system, routing that cord through the arm alongside the hose means switching tools at the same station is quick — unplug one, plug in the next, no cords to untangle first.
This is a good buy for any shop with a Festool CT extractor parked at a semi-permanent station — a dedicated sanding bench, a track saw cutting table, a router table — where the hose and cord currently just pile up on the floor. If you move your extractor between job sites regularly instead of running it from one fixed spot, a wall-mounted arm won't do you much good; this is a workshop fixture, not a jobsite accessory.
Route Hose and Cord Overhead, Not Underfoot

Once the wall bracket is up, the boom arm becomes a permanent overhead routing point for your extraction hose and power cord — no more coiling either one on the floor between cuts or sanding passes.
- Extends to nearly 5 ft. (1.5 m) with 13 modular chain links
- Hook-and-loop straps keep hose and cord bundled along the arm
- Swivels out of the way when the extractor isn't in use

Pro Tip
Don't mount it at full extension right away. Hang the bracket, extend the arm over your usual work position, and pull out however many chain links you don't need — it's a lot easier to remove slack up front than to fight a droopy arm every day after.
Tool Nut's Take
The Fix for the Hose You Keep Tripping Over
The Festool CT-ASA FLX W Overhead Boom Arm is a simple, permanent solution to a problem every shop with a dust extractor eventually runs into: hose and cord piling up at your feet.
- Who it's for: Woodworkers and shop owners running a Festool CT extractor from a fixed station — a sanding bench, cutting table, or router setup.
- Why it stands out: The modular chain-link design lets you dial in the exact reach you need, and the swivel mount means it's never in your way when you don't want it there.
- Worth knowing: This is a workshop fixture, not a portable accessory — it's a permanent wall install, so it makes the most sense at a station you use regularly, not one you're constantly relocating.
Common Questions
- Which Festool dust extractors does this fit? The CT-ASA FLX W is designed for the Festool CT 26 through CT 48 dust extractors.
- Can I shorten the arm? Yes. The chain links are modular, so you can remove links to reduce the extended length if you don't need the full nearly-5-foot reach.
- Does this come with the dust extractor or hose? No. This kit includes the boom arm, wall bracket, and hook-and-loop fastener only — the extractor and hose are sold separately.
- Is the wall bracket a permanent installation? Yes, it's designed to be mounted to most wall types for a stable, permanent setup rather than removed and reinstalled regularly.
