FSB Bypass Framing Fixed-Clip Strut Connector

FSB

On This Page

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.)

Load Table - FSB Allowable Connector Loads (lb.)
  1. For additional important information, see Innovative Solutions for Curtain-Wall Framing.
  2. 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.
  3. Min. fasteners quantity and tabulated values – fill round holes; max. fasteners quantity and tabulated values – fill round and triangle holes.
  4. 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.
  5. Tabulated F4 values are controlled by 1/8" deformation limit. The connector strength load in the F4 direction is 550 lb.
  6. 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.)

Load Table - FSB Allowable Anchorage Loads (lb.)
  1. 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.
  2. 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.
  3. 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.
