Durable ABS flex bracket for new construction can be nailed, stapled, or screwed to joists before drywall is cut and installed. The speaker then installs using its Roto-Lock™ clamps. The Flex Bracket's snap-on mesh metal wings will accommodate up to 24-inch (610mm) on-center installations. It can be used with all Visual Performance Series, C6R, and Professional Series round in-ceiling speakers
