Installation to Wood Joist Ceilings
Use a stud fi nder to locate the edges of the joist. Use of an edge-to-edge stud fi nder is highly recommended.
Based on its edges, draw a vertical line down the joist’s center. Place ceiling plate (A) on ceiling as a template,
making sure that the two mounting slots are on the stud centerline.
Note: Opening on outer channel (B) indicates front of mount. Use the correct mounting slots on the ceiling plate
depending on ceiling joist orientation as shown in fi gure 2.1 or fi gure 2.2. Mounting slots on ceiling plate allow for
45° (
±
22.5) of swivel adjustment before securing to joist.
Mark the center of the two mounting holes depending on joist orientation as shown in fi gure 2.1 or fi gure 2.2. Drill
two 5/32" (4 mm) dia. holes 2-1/2" (65 mm) deep. Secure ceiling plate (A) to wood joist using two #14 x 2-1/2"
wood screws (H) as shown.
Skip to step 3.
• Installer must verify that the supporting surface will safely support the combined load of the equipment and all
attached hardware and components.
• Tighten wood screws so that ceiling plate is fi rmly attached, but do not overtighten. Overtightening can damage the
screws, greatly reducing their holding power.
• Never tighten in excess of 80 in. • lb (9 N.M.).
• Make sure that mounting screws are anchored into the center of the stud or joist. The use of an "edge to edge" stud
fi nder is highly recommended.
• Hardware provided is for attachment of mount through standard thickness drywall or plaster into wood studs or
joists. Installers are responsible to provide hardware for other types of mounting situations (not evaluated by UL).
