Installation Information
- Baffles can be hung above or below ceiling lights.
- The distance between hanging baffles and the ceiling has little effect on acoustic performance.
Wall-to-Wall Cable Mount Installation
- Recommended for large, open areas.
- Baffles are arranged parallel with each other.
- Spacer bars may be used for arrangement and placement of baffles along the cable span.
Ceiling Mount Installation
- Avoid hanging baffles more than 10 feet below ceiling. Long tethering may cause baffles to sway in areas with strong air currents.
- Use 1/16" cable or lightweight chain to hang baffles from the ceiling.
- Attach cable or chain to ceiling by looping it around ceiling joists or trusses. (Anchoring eyes can also be used. Install them into the ceiling before you begin.)
- Once cable or chains are in place, attach the bottom end of the cables or chains to the eye loop on top of the corkscrew hanger.
- Baffles can be aligned in the same direction or arranged so that every other baffle is turned 90 degrees.
