The Festool 576802 PLANEX Drywall Sander Harness TG-LHS 225 w/ Systainer3 is a support harness system for Festool long-reach drywall sanders. This is a drywall sander accessory designed for overhead sanding and long sessions on walls and ceilings. Model Number 576802. If you use a PLANEX on ceiling work, this accessory matters because it helps reduce strain, improves control, and makes it easier to keep working at a steady pace.

What makes this setup useful is not just that it holds the tool, but how it changes the feel of the job. The harness is built as a working aid for sanding ceilings with the PLANEX LHS 225 EQ, and it is also compatible with PLANEX 2, PLANEX EASY, and original PLANEX sanders. Instead of fighting the leverage of a long drywall sander above shoulder height, the harness helps support the tool so the operator can focus on keeping the sanding head flat and moving evenly. That translates into more consistent drywall finishing and less wasted energy.

Festool also built in a symmetrical auxiliary handle for one-handed or two-handed guidance. On a long-reach drywall sander, that extra control is a big deal. It gives you another stable contact point when you are reaching across a ceiling or feathering over seams and patches. For finish work, control is what keeps sanding even and helps avoid gouging or uneven pressure.

The fit range is practical for a real crew. The harness adjusts for users from 5 feet 3 inches to 6 feet 3 inches, which covers a broad range of operators without turning this into a one-person accessory. When combined with an extension, it can reach ceilings up to 8-1/2 feet high. That makes it a smart add-on for remodeling, drywall finishing, and punch-list work in standard interior spaces where overhead sanding is routine.

Jobsite practicality is another strong point here. The attachment and removal process does not require tools, so setup stays quick when you need to move from room to room or switch between supported and unsupported use. The included Systainer SYS3 XXL 237 also matters more than it sounds. A harness system with multiple parts is only convenient if it stores cleanly and travels well, and the Systainer keeps the setup organized instead of getting pieced out in the van or trailer.

This accessory is best suited for drywall contractors, remodelers, painters doing prep, and serious users already invested in the Festool PLANEX platform. If you only sand occasionally, you may not need it. If overhead drywall sanding is part of your regular work, the Festool 576802 PLANEX Drywall Sander Harness TG-LHS 225 w/ Systainer3 is the kind of accessory that pays off in reduced fatigue, better handling, and a more controlled sanding process from the first room to the last.
