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.
