solid concrete
cinder block
• When installing Peerless mounting bases on cinder block, verify that you have a minimum of 1-3/8" 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" minimum from the side of the block. Cinder block must meet ASTM C-90 specifi -
cations. 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.
