BridgeBar® Light Steel Bridging Channel 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. BridgeBars standard U-channel shape ensures use through ¾ and 1½ stud punchouts.
BridgeBar is available in ¾" and 1½" widths. Designations are BB75 and BB150.
