BridgeBar® Bridging Channel
BridgeBar® replaces cold-rolled channel (CRC) for wall bridging. Unique grooves every 4” trap the 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

Section Properties and Allowable Loads
Notes:
- Gross section properties are calculated based on the minimum dimensions of the cross section.
- Effective section properties and allowable loads for BridgeBar are calculated based on AISI S100-16 / S1-18 / S2-20 Specification.
- Effective section modulus (Sxe) is calculated based on the minimum dimensions of the cross section.
- Effective area (Ae) and allowable axial load (Pa) are calculated based on the average dimensions of the cross section.
- Use BridgeClip® for a quick and easy method of securing BridgeBar® to stud (when required).
- Resists compressive loads through the plane of the wall.
- Use through 3/4″ or 1-1/2″ stud punchouts.
