Installation to Concrete Ceilings
WARNING
•When installing Peerless mounts on concrete, verify that you have a minimum of 1 5/8" of actual concrete surface in the 1/4" diameter hole to be used for the concrete anchors. Do not drill into mortar joints! Concrete must meet ASTM
•Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor.
•Make sure that the supporting surface will safely support the combined load of the equipment and all attached hard- ware and components.
•Never exceed the Maximum UL Load Capacity of 50 lb (22.7 kg).
1 | NOTE: ACC203 (Alligator concrete anchors are not |
included) are recommended. |
Drill two 1/4" (6 mm) dia. holes to a minimum depth of 2.5" (64 mm). Attach ceiling plate (G) using two concrete anchors and #14 x 2.5" wood screws (F) as shown in Illustration A and 1, 2 and 3. Tighten all fasteners.
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.
WARNING
•Tighten wood screws so that wall plate is firmly 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.).
WARNING
•FOR DIRECT ATTACHMENT TO LOAD BEARING CONCRETE ONLY! Concrete expansion anchors are not intended for attachment to concrete ceilings covered with a layer of plaster, drywall, or other finishing material. If mounting to concrete ceiling covered with plaster / drywall is unavoidable, plaster / drywall must be counterbored as shown below.
