FSB Bypass Framing Fixed-Clip Strut Connector
The FSB connector is the fixed-clip version of our popular SSB slide-clip strut connector. The FSB is commonly used at the bottom flange of a steel beam to accommodate large standoff distances for bypass curtain-wall studs.
- Use the specified type and number of anchors.
- Use the specified type and number of screw fasteners to the stud.
- If the FSB intrudes on interior space, it can be trimmed. The trimmed part shall allow an edge distance of 1/2" or greater from the center of the nearest anchor to the end of the trimmed part.
- FSB3.518-R25 is a box of 25 connectors

FSB Allowable Connector Loads (lb.)
- For additional important information, see Innovative Solutions for Curtain-Wall Framing.
- FSB Allowable Connector Loads are also limited by the FSB Allowable Anchorage Loads table. Use the minimum value from the connector and anchorage load tables as applicable.
- Min. fasteners quantity and tabulated values – fill round holes; max. fasteners quantity and tabulated values – fill round and triangle holes.
- Tabulated F1 loads are based on assembly tests with the load through the centerline of stud. Tested failure modes were due to screw pullout; therefore compare F1 against Fp calculated per ASCE 7-10 Chapter 13 with ap = 1.25 and Rp = 1.0.
- Tabulated F4 values are controlled by 1/8" deformation limit. The connector strength load in the F4 direction is 550 lb.
- Maximum standoff for FSB is 11" with two anchors to primary structure and 10" with four anchors to primary structure.
FSB Allowable Anchorage Loads (lb.)
- Allowable loads for #12-24 self-drilling screws and PDPT powder-actuated fasteners are based on installation in minimum 3/16" thick structural steel with Fy = 36 ksi. It is the responsibility of the designer to select the proper length fasteners.
- Allowable loads for welded connections require E70XX electrodes with a minimum throat size equal to the clip thickness. Welding shall comply with AWS D1.3. Welding galvanized steel may produce harmful fumes; follow proper welding procedures and precautions.
- Allowable loads are for anchorage only. It is the responsibility of the designer to verify the strength and stability of the structure for loads imposed by the cold-formed steel framing connections.
