SIMPSON STRONG-TIE FSB Bypass Framing Fixed-Clip Strut Connector, 3.5 in. x 18 in., 16-Ga Galvanized Steel, Box of 25 – FSB3.518-R25

The Simpson Strong-Tie FSB is the fixed-clip version of the SSB slide-clip strut connector, made from 54 mil (16 ga.) G90 galvanized steel. This 3.5 in. x 18 in. bypass framing connector is commonly used at the bottom flange of a steel beam to accommodate large standoff distances for bypass curtain-wall studs. One box contains 25 connectors.

Key Features

• Bypass framing: Fixed-clip connector designed for bypass curtain-wall stud applications.
• Large standoff: Commonly used at the bottom flange of a steel beam to accommodate large standoff distances.
• 16-ga steel: Made from 54 mil (16 ga.) steel for rigid cold-formed steel construction.
• G90 galvanized: Galvanized (G90) finish for corrosion resistance.
• Trimmable design: If the FSB intrudes on interior space, it can be trimmed while maintaining a 1/2 in. minimum edge distance to the nearest anchor.
• Box of 25: Each box (FSB3.518-R25) contains 25 connectors.

Frequently Asked Questions

What is included?

One box containing 25 FSB3.518 fixed-clip strut connectors, each 3.5 in. x 18 in. in 16-ga galvanized steel.

What is the difference between FSB and SSB?

The FSB is the fixed-clip version of the SSB slide-clip strut connector; the FSB does not allow sliding deflection.

Where is this connector used?

It is commonly used at the bottom flange of a steel beam to accommodate large standoff distances for bypass curtain-wall studs.

What fasteners do I need?

Use the specified type and number of anchors to the structure and screw fasteners to the stud per the Simpson load tables.

Can it be modified on site?

Yes, if it intrudes on interior space it can be trimmed, keeping at least 1/2 in. edge distance from the center of the nearest anchor to the trimmed end.

Is it corrosion resistant?

Yes, the connector is made from 54 mil (16 ga.) steel with a G90 galvanized finish.

Product Expert Notes

Choose the FSB where bypass curtain-wall studs must connect to structure over a large standoff and no deflection slip is required; specify the SSB slide-clip instead where vertical building movement must be accommodated. Always match anchors and screws to the published load tables for the required loads. Keep a few spare connectors on hand for trimmed or field-modified conditions.

Structural connector installation must follow the manufacturer's load tables and be performed by qualified installers using the specified anchors and fasteners; consult the project engineer of record.
