Computer modeling and CNC manufacturing enables glulam to be delivered to the jobsite in precise lengths and with preinstalled concealed hangers. The Simpson Strong-Tie CBH Concealed Glulam Beam Hanger (CBH2.37X5.5H-KT) is specifically designed for such applications, and is installed with readily available Strong-Drive SDS Heavy-Duty Connector screws. Manufactured from heavy 3-gauge steel with a hot-dip galvanized finish for superior corrosion resistance, this hanger is engineered to deliver both architectural aesthetics and proven structural performance. The CBH has been tested for inter-story drift and has achieved 1-hr and 2-hr fire resistance ratings according to ASTM E119, making it a trusted solution for exposed and fire-rated construction.

Key Features

• Concealed design for architectural aesthetics and fire-rated performance
• Multiple router options to suit jobsite needs
• +/- 1/32 in. beam length tolerance on each end enables easier installation
• 1-hr and 2-hr fire resistance ratings per ASTM E119
• Inter-story drift performance tested to over 2%
• Code-listed per ICC-ESR-2552
• 3-gauge steel construction for heavy-duty structural integrity
• Hot-dip galvanization (HDG) offers extra corrosion resistance for exterior and treated-wood applications
• Two backplates make up one complete connection
• Made in the United States

Frequently Asked Questions

What screws are required to install the CBH2.37X5.5H-KT?

The required fasteners depend on the application. For a joist-to-beam application, use (13) Strong-Drive SDS25300 screws and (13) Strong-Drive SDS25600 screws. For a joist-to-column application, use (26) Strong-Drive SDS25600 screws. Note that screws are not included with the hanger kit - the package includes only the two backplates that make up one complete connection.

Does this hanger meet fire resistance requirements?

Yes. The CBH2.37X5.5H-KT has achieved both 1-hour and 2-hour fire resistance ratings tested according to ASTM E119. Its concealed design contributes to this fire-rated performance, making it suitable for applications where fire resistance is required.

Is this hanger suitable for exterior or treated-wood applications?

Yes. The CBH2.37X5.5H-KT is manufactured from 3-gauge steel with a hot-dip galvanized (HDG) finish, which provides extra corrosion resistance. This makes it appropriate for exterior applications and use with treated wood where enhanced protection against corrosion is needed.

What code listings apply to this product, and what are its key dimensions?

The CBH2.37X5.5H-KT is code-listed per ICC-ESR-2552. It measures 2-3/8 in. wide by 5-1/2 in. tall. Additionally, its +/- 1/32-in. beam length tolerance on each end provides flexibility during installation, and inter-story drift performance has been tested to over 2%.
