FSB Bypass Framing Fixed-Clip Strut Connector
On This Page
Product Details
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.
Material
- 54 mil (16 ga.)
Finish
- Galvanized (G90)
Installation
- 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.
Ordering Information
- FSB3.518-R25 is a box of 25 connectors

Load Tables
FSB Allowable Connector Loads (lb.)
- See General Information and Notes.
- 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.
- Allowable F1 loads are based on in-plane loads applied to the stud fasteners that are nearest the support with complete rotational restraint at the studs. For more extensive treatment of in-plane loads please refer to Simpson Strong-Tie engineering letter L-CF-CWCF1DIR17.
- Tabulated F4 values are controlled by 1/8" deformation limit. The connector strength load in the F4 direction is 550 lb.
FSB Allowable Anchorage Loads (lb.) Anchorage Type
- 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.
FSB Bypass Framing Fixed-Clip Connector — Service Load Limits, LRFD Design Strengths and Nominal Strengths
- Tabulated values are for the connector and attachment to the stud-wall framing. The assembly strengths are the minimum of those listed and the anchorage values listed in the Anchor Values table below.
- Service Load Limit is the load at 1/8" deflection for use in evaluating the performance under service-level loads.
- LRFD Design Strength is the Nominal Strength multiplied by a resistance factor, φ.
- Nominal Strength is defined in AISI S100-07.
Anchor Values (lb.) in F1, F2, F3, and F4 Direction for FSB
- Tabulated values are for the anchorage only. The assembly strengths are the minimum of those listed above and the connector capacity and attachment to the stud-wall framing listed in the FSB Service Load Limits, LRFD Design Strengths and Nominal Strengths table above.
- LRFD Design Strength is the Nominal Strength multiplied by a resistance factor, φ.
- Nominal Strength is defined in AISI S100-07.
- For the Service Load Limit, use the values listed for the connectors in the FSB Service Load Limits, LRFD Design Strengths and Nominal Strengths table above.
