plate is fi rmly attached. Snap end caps (L) into
place.
For Concrete Ceilings drill four 5/16"(8 mm) dia.
holes to a minimum depth of 1 3/4" (45 mm). Attach
ceiling plate (K) using concrete expansion anchors
as shown in 2-1 and 2-2. Then snap end caps (L)
into place.
Align hole in ceiling plate with hole in ceiling.
Gently hammer in concrete anchor.
Use a 10 mm wrench to tighten concrete anchor
to 80 in • lb (9 N.M.) maximum torque to expand
anchors.

• Tighten wood screws so that ceiling plate is fi rmly
attached, but do not overtighten. Overtightening
can damage 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 joists. The use of an "edge to edge"
stud fi nder is highly recommended.
