BridgeBar®

BridgeBar® replaces cold-rolled channel (CRC) for wall bridging. Unique grooves every 4” trap stud web to allow installers to space any type of wall layout. The grooves adjust to various stud thickness to trap the stud web for maximum strength. BridgeBar incorporates stiffeners to resist compressive loads through the plane of the wall. BridgeBar’s standard U-channel shape ensures use through ¾” and 1½” stud punchouts.

Features
  • Fast installation
  • Notches every 4″ accommodate 8″, 12″, 16″, 24″ centers
  • No clamping
  • No welding
  • Load rated assembly
  • 52-inch length allows for 4″ lap at joints for continuous walls
  • Guide holes for placement when BridgeClip® is used

BridgeBar® Applications

 

BridgeBar - Bridging Channel - Application

Wall Bridging Channel

Installation Instructions

  1. Run BridgeBar through stud punchouts.
  2. Locate grooves at bottom of punchout and press down into place.
BridgeBar - Bridging Channel - Installation Lap Joint

Lap Joints

BridgeBar’s 52” length allows for a 4” overlap at joints. Simply fit one end over the other and line up the guide holes for quick & easy placement of screw(s). Joint locations maintain stud spacing as designed through length of the wall system.

Notes:

  1. Use BridgeClip® for a quick & easy method of securing BridgeBar to stud (when required)
  2. Resists compressive loads through the plane of the wall
  3. Use through ¾” and 1½” stud punchouts.
  4. Gross section properties are calculated based on the minimum dimensions of the cross section.
  5. Effective section properties and allowable loads for BridgeBar are calculated based on AISI S100-2007 Specification.
  6. Effective section modulus (Sxe) is calculated based on the minimum dimensions of the cross section.
  7. Effective area (Ae) and allowable axial load (Pa) are calculated based on the average dimensions of the cross section.
