Product Description
The Simpson CBH2.37X9.75C-KT CBH 2-3/8 in. x 9-3/4 in. Joist-to-Column Concealed Hanger with Screws by Simpson is an engineered concealed beam hanger purpose-built for glulam joist-to-column connections. Computer modeling and CNC manufacturing enables glulam to be delivered to the jobsite in precise lengths and with preinstalled concealed hangers, and this hanger is specifically designed for such applications. Installed with Strong-Drive SDS Heavy-Duty Connector screws that are included in the kit, the CBH delivers a clean, hidden connection that supports both architectural intent and fire-rated construction requirements.
Key Features
- Fully concealed design - keeps the connection hidden from view for a clean architectural finish while contributing to fire-rated wall and floor assemblies
- Multiple router options - gives installers the flexibility to adapt to different jobsite conditions without sourcing additional components
- +/- 1/32 in. beam length tolerance on each end - reduces the need for field trimming and allows faster, more forgiving installation of precut glulam members
- 1-hr and 2-hr fire resistance ratings per ASTM E119 - meets code requirements for fire-rated construction, broadening the range of projects where this hanger can be specified
- Inter-story drift performance tested to over 2% - demonstrates structural reliability under lateral movement, suitable for demanding seismic and wind load applications
- Code-listed per ICC-ESR-2552 - provides the documentation engineers and inspectors need for plan approval and compliance verification
- 3-gauge steel with electrogalvanized finish - heavy-gauge construction delivers robust load capacity, while the finish provides corrosion resistance for long-term performance
- Two-backplate connection system included in one kit - both backplates and all 46 Strong-Drive SDS25600 screws are included, so the complete connection arrives ready to install
Why This Product
- A complete, install-ready kit - with both backplates and 46 Strong-Drive SDS25600 screws included, there is no need to source fasteners separately, saving time on procurement and reducing the risk of mismatched hardware on the job
- Engineered for modern mass timber construction - the CBH is purpose-designed to work with CNC-cut glulam beams delivered to precise lengths, making it a natural fit for prefabricated and modular timber framing workflows
- Dual fire ratings support a wider project scope - achieving both 1-hr and 2-hr fire resistance ratings per ASTM E119 from a single concealed hanger means fewer product substitutions when project fire ratings change during design
- Tested and code-listed for structural confidence - inter-story drift testing exceeding 2% combined with ICC-ESR-2552 code listing gives structural engineers and building officials verifiable performance data to support specifications and inspections
