Installation To Wood Joist Finished Ceilings, Exposed Wood Joists, or Wood Beam Ceilings Drill two 5/32" (4 mm) dia. holes to a minimum depth of 2.5" (64 mm). Attach ceiling plate (J) to ceiling with two #14 x 2.5" wood screws (Q) using 3/8" (10 mm) socket wrench as shown in figure 1.1. NOTE: For optional cord management, install two spacers (K) between ceiling plate (J) and ceiling as shown in figure 1.2. Skip to step 2 for flush mount installation. Skip to step 3 for extension column installation. WARNING • Tighten wood screws so that ceiling plate is firmly attached, but do not overtighten. Overtightening can damage the screws, greatly reducing their holding power. - Page 4 Installation to Concrete Ceilings • Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor. • Installer must verify that the supporting surface will safely support the combined load of the equipment and all at- tached hardware and components. Drill two 5/16" (8 mm) dia. holes to a minimum depth of 2.5" (64 mm). Insert anchors (O) in holes flush with wall. Place ceiling plate (J) over anchors and secure using two #14 x 2.5" screws (Q). IMPORTANT: It is the responsibility of the installer to verify that the ceiling will safely support the combined load of all attached hardware and components. Skip to step 2 for flush mount installation. Skip to step 3 for extension column installation. WARNING • Tighten wood screws firmly, but do not overtighten.
