Product Description
The Simpson CBH Concealed Glulam Beam Hanger, 2-3/8 in. x 5-1/2 in., is an engineered joist-to-beam connector built for glulam construction where concealment, fire performance, and precision installation all matter. Computer modeling and CNC manufacturing enable glulam beams to arrive at the jobsite in exact lengths with hangers preinstalled, and this connector is specifically designed to support that workflow - installed using Strong-Drive SDS Heavy-Duty Connector screws that are included in the kit. With verified fire resistance ratings and tested drift performance, it meets the structural and aesthetic demands of modern timber framing projects.
Key Features
- Fully concealed profile - keeps the connection hidden within the beam for a clean architectural finish while also contributing to fire-rated assembly performance
- +/- 1/32-in. beam length tolerance on each end - accommodates minor dimensional variation in glulam beams, reducing fit-up problems and speeding up installation
- 1-hr and 2-hr fire resistance ratings per ASTM E119 - qualifies the connection for fire-rated floor and roof assemblies without requiring additional protection at the joint
- Inter-story drift performance tested to over 2% - confirms the connector can handle lateral movement demands common in seismic and wind-load design scenarios
- Code-listed per ICC-ESR-2552 - simplifies plan review and inspection approval by providing a recognized third-party evaluation report
- Multiple router options available - gives contractors flexibility to match jobsite tooling and beam preparation methods without compromising the connection
- Made from 3-gauge steel with an electrogalvanized finish - delivers heavy-duty structural capacity with corrosion resistance suited to typical interior timber framing environments
- Kit includes two backplates plus all required screws - everything needed for one complete joist-to-beam connection arrives together, eliminating the need to source fasteners separately
Why This Product
- Designed specifically for preinstalled glulam applications - the CBH works in direct alignment with CNC-precision glulam delivery, meaning the hanger can be factory-set before the beam ever reaches the site, cutting field labor and reducing installation complexity
- Dual fire ratings support a wider range of assembly requirements - achieving both 1-hr and 2-hr ratings per ASTM E119 means a single connector model covers multiple project specifications without substitutions or engineering workarounds
- A complete, ready-to-install kit - the included Strong-Drive SDS25300 and SDS25600 screws are the exact fasteners required for the joist-to-beam application, so nothing is missing and no separate hardware order is needed
- Concealment delivers both visual and performance benefits - unlike surface-mounted hangers, the hidden installation protects the connection aesthetics in exposed timber ceilings and contributes directly to the fire-rated assembly rating

Frequently Asked Questions
What fasteners are required to install the CBH2.37X5.5B-KT, and are they included?
This kit is installed with (13) Strong-Drive SDS25300 screws and (13) Strong-Drive SDS25600 screws for the joist-to-beam application. Both screw types are included in the kit along with the two backplates.
Does this hanger meet fire resistance requirements?
Yes. The CBH concealed beam hanger has achieved both 1-hr and 2-hr fire resistance ratings according to ASTM E119, making it suitable for applications with fire-rated assembly requirements.
How does the beam length tolerance feature benefit installation?
The CBH2.37X5.5B-KT provides a +/- 1/32-in. beam length tolerance on each end, which accommodates minor variations in glulam beam length and enables easier, more forgiving installation on the jobsite.
Is the CBH2.37X5.5B-KT code-listed, and has it been tested for seismic or drift performance?
Yes. This connector is code-listed per ICC-ESR-2552 and has been tested for inter-story drift performance, achieving results in excess of 2%, supporting its use in seismic and lateral load applications.
