• Use all specied fasteners. See Product Notes, page 18.
• Use a minimum of two anchors per mudsill. An anchor should always be within 12"
of the end of each mudsill section. Follow spacing guidelines in chart.
• Do not rely on these anchors to secure concrete sections together between cold joints.
• Spread sill anges to mudsill width prior to insertion into wet concrete (minimum
strength of 2,500 psi). Alternate installation is possible by inserting unbent anges
through 3/4" center hole pre-drilled in mudsill. Foundation anchors may also be
attached to mudsill and then inserted into wet concrete. When installing ST2-TZ
into concrete block, ll cells with grout with a minimum strength of 2,500 psi.
Concrete block edges may need to be beveled to facilitate installation.
• ST2-TZ in masonry construction shall be installed in the core of the block and
grouted with concrete grout designed for that purpose. In no case, shall they be
installed in a mortar joint.
• Do not use in red clay brick.
