| FAST™ COMPONENTS
The FAST™ system consists of a FAST™ bracket,
anchor bolt, (optional) Shim Plates and Wedge Shims, and
a retaining pin. FERO supplies the FAST™ bracket,
shims, and retaining pin. The anchor bolt and shelf angle
are obtained readily from local suppliers.
All steel components supplied
by FERO, including the FAST™ brackets,
Shim Plates and Wedge Shims, bolt washers, and retaining
pins are hot dipped galvanized after fabrication in accordance
with ASTM A123. FERO brackets, Shim Plates, and bolt washers
are manufactured from 4.76 (3/16") mild steel plate.
A series of standard bracket sizes is available to accommodate
various cavity design widths. For example, if the FAST™ bracket
were to support a masonry veneer that includes a 51 mm (2")
insulation and a 25 mm (1") air space, the required
size of bracket would be 51 mm (2") + 25 mm (1")
= 76 mm (3"). Figure 1 shows the bracket specification
depth labeled as "D", which is the width of the
cavity (air space and insulation). The bracket specification
depth, or "Bracket Size", is available in 12.7
mm (1/2") increments, extending from a cavity width
of 25 mm (1") to 165 mm (6-1/2"). The slot in the
back of the bracket is designed to receive one 15.9 mm (5/8")
diameter bolt and allows for 45 mm (1-3/5") of vertical
adjustability. The slot is placed at a +/- 22.5 degree angle
from the vertical, which reduces the likelihood of bracket
slippage under load. When two or more brackets are used,
and adjacent brackets are installed so as to alternate the
orientation of the slot as illustrated in Figure 3, bracket
slippage becomes prohibitive. An oversize, 5 mm (3/16")
thick rectangular washer is supplied by FERO, and is required
for use with the anchor bolt; standard round washers should
not be used. The FAST™ system is designed to receive
a 100 x 100 x 6 mm (4" X 4" X 1/4") angle.
The optional Shim Plate is sized and configured to fit the
back surface of the bracket and provide full bearing. Figure 1 shows a typical detail of the system installed on concrete
structural backing. |
