Level and use wall plate as template to mark center 

of holes. Drill two 5/16" (8 mm) dia. holes to a 

minimum depth of 2.5" (64 mm). Insert anchors (

B) 

in holes flush with wall. Place wall mount (

A) over 

anchors and secure with wood screws (

H). Make 

sure wall mount is level, and tighten all fasteners.

•  When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" (35 mm) of actual 

concrete thickness in the hole to be used for the concrete anchors. Do not drill into mortar joints! Be sure to mount 

in a solid part of the block, generally 1" (25 mm) minimum from the side of the block. Cinder block must meet 

ASTM C-90 specifications. It is suggested that a standard electric drill on slow setting is used to drill the hole 

instead of a hammer drill to avoid breaking out the back of the hole when entering a void or cavity.

•  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 

hardware and components.

•  Tighten screws so that wall plate is firmly 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.).

•  Always attach concrete expansion anchors directly to 

load-bearing concrete.

•  Never attach concrete expansion anchors to concrete 

covered with plaster, drywall, or other finishing mate-

rial. If mounting to concrete surfaces covered with a 

finishing surface is unavoidable, the finishing surface 

must be counterbored as shown below. Be sure con-

crete anchors do not pull away from concrete when 

tightening screws. If plaster/drywall is thicker than 

5/8" (16 mm), custom fasteners must be supplied by 

installer. (not evaluated by UL)

Drill holes and insert anchors (

B).

Place plate (

A) over anchors (B) and secure with screws (H).

Tighten all fasteners.
