Peerless Industries UST-WallArm3 Manuel D’Utilisation

CINDER

BLOCK

SOLID

CONCRETE

•  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 wall will safely support four times 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 material. If mounting to concrete surfaces

covered with a finishing surface is unavoidable),

the finishing surface must be counterbored as

shown below. Be sure concrete 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.

Make sure that wall arm bracket (

C) is level, use it as

a template to mark four mounting holes. Drill four 5/16"

(8 mm) dia. holes to a minimum depth of 2.5" (64 mm).

Insert concrete anchors (

K) in holes flush with wall as

shown (right). Place wall arm bracket over anchors and

secure with #14 x 2.5" screws (

J). Level, then tighten all

fasteners.
