SOLID CONCRETE
CINDER BLOCK
1/4"
Installation to Solid Concrete or Cinder Block
• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" (35 mm) of actual con-
crete 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 specifica-
tions. 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.
WARNING
Place wall plate ( B) on wall as a template. Level, and mark the center of the three mounting holes. Drill three 5/16"
(8 mm) dia. holes to a minimum depth of 2.5" (64 mm). Insert anchors ( P) in holes flush with wall as shown. Fasten
two #14 x 2.5" wood screws ( O) leaving 1/4" of thread exposed as shown in Figure 4.3.
Hook wall plate ( B) onto exposed #14 x 2.5" wood screws (O). Secure using one #14 x 2.5" wood screws (O) as
shown in figure 4.4. Skip to Step 5.
