BuckleBridge® provides a solid wall stud bridging system to resist weak axis buckling and torsional rotation of members in load bearing wall and curtain wall applications. Elongated tabs in one end of BuckleBridge lock into a slot at the other end (through the stud knockout). Two vertical flaps at each end contain predrilled holes to facilitate the attachment to the stud in load bearing applications.  BuckleBridge is used with 16” o.c. member spacing.


  • Fast installation
  • Tabs lock into slots for continuous system
  • No threading channels through knockouts
  • No welding
  • Meets AISI bridging stiffness requirements
  • Guide holes for accurate placement of fasteners to stud
  • Fits in SigmaStud® and standard "cee" wall sections, 6” and 8" web depths
  • Reduces required rows of bridging when compared to other bridging methods such as cold-rolled channel with clips
