Pipe sleeve: Ø4.50” x 0.237” wall x 14.50” long. ASTM A53 Grade B Type E & S, yield
strength = 35 ksi (min.), tensile strength = 60 ksi (min.).

Pier Tube: Ø4.00” x 0.226” wall x 36” long. ASTM A500 Grade B or C, yield strength = 50 ksi (min.),
tensile strength = 62 ksi (min.). Ø3.50” x 0.216” wall x 8” long internal coupler at one end
with 4” extending out of pier tube.

Pier Starter Tube: Ø4.00” x 0.226” wall x 36” long. ASTM A500 Grade B or C, yield strength = 50 ksi (min.),
tensile strength = 62 ksi (min.). Ø4.50” x 0.237” wall x 1” long friction reducing collar
welded to one end.

Pier Cap: 4.00” wide x 8.50” long x 1.25” thick plate with pier locator plate welded to one side. ASTM A572 Grade 50, yield strength = 50 ksi (min.), tensile strength = 65 ksi (min.).
All-Thread Rod: Ø0.875” x 18” long, zinc plated. ASTM A193 Grade B7, tensile strength = 125 ksi (min.).

Allowable System Capacity: 39,000 lbs. (with FS400BV Bracket)

Notes:

1.Retrofit brackets shall be used for support of structures that are considered to be fixed from translation. Structures that are not fixed from translation shall be braced in some other manner prior to installing retrofit bracket systems.

2.Concrete bearing assumes a minimum compressive strength (f’c) of 2,500 psi. Local concrete bending and other local design checks should be evaluated on a case by case basis by the project engineer.

3.Mechanical capacity is based on continuous lateral soil confinement in soils with SPT blow counts ≥ 4. Piles with exposed unbraced lengths or piles placed in weaker or fluid soils should be evaluated on a case by case basis by the project engineer.
