sure that the mounting holes are in the center of the wood joist. Drill two 5/32" (4 mm) dia. holes to a minimum depth

fl at washers (E) as shown in fi gure 2.1 or fi gure 2.2 depending on joist orientation.

• 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 projector mount assembly 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. 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. Install-
ers are responsible to provide hardware for other types of mounting situations (not evaluated by UL).
