Installation to Solid Concrete and Cinder Block
1
• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" 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" minimum from the side of the block. Cinder block must meetASTM 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
breakingout the backof the hole when enteringa void orcavity.
• Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor.
• Make sure that the wall will safely support the combined load of the equipment and all attached hardware and
components.
WARNING
Removecord covers from wall armassembly (A) as
shown in figure 1.6. Level and use wall plate as
template to mark center of holes. Drill two 1/4" (6
mm) dia. hole to a minimum depth of 2" (51 mm).
Insert anchors (H) in holes flush with wall as shown in
fig1.8. Placewall arm(A) over anchor and secure
with wood screw (I) as shown in figures 1.9 and 1.11.
Make sure wall arm is level, and tighten all fasteners.

toconcrete wall coveredwith plaster/drywall is
unavoidable,plaster/drywall (up to5/8" thick) mustbe
