and Slab Push Pier
Bracket Assemblies
The FSI push pier product line includes multiple
shaft sizes and bracket assemblies to account
for most typical system uses and applications. A
summary table of the products and system use
categories is presented as
Figure 3.4.a
. Bracket
systems are categorized by their design or
system use and include under-footing brackets,
flush-mount brackets and slab pier brackets. The
bracket assemblies again include the bracket,
pier cap, external sleeve (if applicable), and
all associated hardware. Crawl space systems
utilize under-footing bracket assemblies with
a shorter external sleeve. These systems are
designated with part numbers starting with
“CS”. Part numbers with a “CR” designation
identify assemblies with coil rods; otherwise, the
assembly comes with threaded rods.
