Product Description
The Simpson CBH Concealed Glulam Beam Hanger is engineered for modern mass-timber and glulam framing projects where hidden hardware is both a structural requirement and an architectural priority. Designed to work with CNC-manufactured glulam delivered to the jobsite in precise lengths with preinstalled hangers, this connector installs using readily available Strong-Drive SDS Heavy-Duty Connector screws and delivers verified fire-rated and drift-tested performance in a fully concealed profile. Each 10-pack includes 20 backplates making 10 complete connections, ready for demanding joist-to-beam or joist-to-column applications.
Key Features
- Concealed design for architectural aesthetics and fire-rated performance - keeps hardware hidden from view while meeting 1-hr and 2-hr fire resistance ratings per ASTM E119, eliminating the need to choose between appearance and code compliance.
- +/- 1/32-in. beam length tolerance on each end - accommodates minor dimensional variation in CNC-cut glulam, reducing field adjustments and speeding up installation.
- Inter-story drift performance tested to over 2% - provides confidence in lateral load performance for structures in seismic or wind-sensitive regions.
- Multiple router options to suit jobsite needs - gives installers flexibility to match the connection method to the specific conditions of each project.
- 3-gauge steel construction with electrogalvanized finish - delivers heavy-duty structural capacity with corrosion resistance suited to exposed or semi-protected framing environments.
- Code-listed per ICC-ESR-2552 - simplifies plan review and inspections by providing a recognized, independently verified compliance path.
- Installs with Strong-Drive SDS Heavy-Duty Connector screws - uses widely available fasteners, keeping procurement straightforward without requiring proprietary hardware.
Why This Product
- Built for prefabricated glulam workflows - the CBH is specifically designed to work with glulam members that arrive at the jobsite CNC-cut to precise lengths with hangers preinstalled, supporting modern prefabrication methods that reduce on-site labor and minimize errors.
- Dual fire ratings in a concealed connector - achieving both 1-hr and 2-hr fire resistance ratings per ASTM E119 in a fully hidden hanger means this connector satisfies fire code requirements without exposed hardware that would compromise the finished look of timber-frame interiors.
- Verified drift performance for structural confidence - with inter-story drift testing exceeding 2% and code listing under ICC-ESR-2552, this hanger provides the documented performance data that engineers and inspectors need for approval on code-compliant glulam structures.
- Precise tolerances that translate to faster field installation - the built-in +/- 1/32-in. beam length tolerance on each end reduces the likelihood of fit issues during installation, keeping glulam framing projects on schedule.

Frequently Asked Questions
What screws are required to install these concealed beam hangers?
Screws are not included with this package. For a joist-to-beam application, each of the 10 connections requires 18 Strong-Drive SDS25300 screws and 18 Strong-Drive SDS25600 screws. For a joist-to-column application, each connection requires 36 Strong-Drive SDS25600 screws.
What fire resistance ratings has the CBH concealed beam hanger achieved?
The Simpson Strong-Tie CBH has achieved both 1-hr and 2-hr fire resistance ratings per ASTM E119, in addition to being tested for inter-story drift performance to over 2%. It is also code-listed per ICC-ESR-2552.
What does this 10-pack include, and how does the hanger system work?
This package includes 20 backplates, which combine to make 10 complete connections. The concealed hanger is designed for glulam beams that are CNC-manufactured and delivered to the jobsite in precise lengths with the hangers preinstalled. The design accommodates a +/- 1/32-in. beam length tolerance on each end to allow for easier installation.
What material and finish are used on these hangers?
The CBH concealed beam hangers are made from heavy 3-gauge steel with an electrogalvanized finish, providing durability suited for structural framing applications while maintaining the concealed aesthetic required for architectural and fire-rated performance.
