The Simpson CBH2.37X5.5 Concealed Glulam Beam Hanger is an engineered structural connector built for joist-to-beam and joist-to-column applications where hidden hardware, clean sightlines, and fire-rated performance are all required in one solution. Computer modeling and CNC manufacturing enables glulam to be delivered to the jobsite in precise lengths and with preinstalled concealed hangers, and the Simpson CBH is specifically designed for such applications. Fabricated from 3-gauge steel with an electrogalvanized finish and installed using readily available Strong-Drive SDS Heavy-Duty Connector screws, this hanger 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 reliable choice for demanding commercial and structural timber projects.

Key Features

• Concealed design for architectural aesthetics and fire-rated performance - hardware stays hidden within the beam, keeping exposed timber framing visually clean while meeting fire resistance requirements without additional treatment.
• 1-hr and 2-hr fire resistance ratings per ASTM E119 - gives designers and contractors verified fire-rated structural connections, supporting compliance on projects with strict building code fire requirements.
• Inter-story drift performance tested to over 2% - engineered and tested for lateral movement demands, making this hanger suitable for seismic zones and structures subject to dynamic loading.
• +/- 1/32 in. beam length tolerance on each end - built-in dimensional flexibility reduces the need for field trimming or adjustment, saving installation time and minimizing costly rework on precut glulam members.
• Multiple router options to suit jobsite needs - accommodates varying site conditions and installation preferences without requiring special custom fabrication.
• Code-listed per ICC-ESR-2552 - independently evaluated and listed, giving inspectors and project teams confidence in approved use for joist-to-beam and joist-to-column connections.
• 3-gauge steel construction with electrogalvanized finish - heavy-gauge material provides substantial load capacity while the electrogalvanized coating offers corrosion resistance appropriate for structural connector applications.
• Pack includes 20 backplates making 10 connections (screws not included) - backplates arrive ready for installation, so crews can stage multiple connections efficiently without counting out individual components on site.

Why This Product

• Purpose-built for preinstalled glulam applications - because computer modeling and CNC manufacturing now deliver glulam to the jobsite with concealed hangers already in place, the CBH is specifically engineered to work within that precision-cut workflow, reducing field complexity on timber frame and mass timber projects.
• Dual fire ratings in a single hidden connector - achieving both 1-hr and 2-hr fire resistance ratings per ASTM E119 means one concealed hanger solution covers a wide range of fire-rated assembly requirements, reducing the need to source separate hardware for different occupancy types.
• Structural confidence backed by independent code listing and drift testing - code listing under ICC-ESR-2552 combined with inter-story drift testing beyond 2% means this connector meets the documentation and performance standards that structural engineers and building officials expect on commercial and mixed-use projects.
• Installs with readily available screws - no specialty fasteners to track down - compatibility with Strong-Drive SDS Heavy-Duty Connector screws means fasteners are easy to source separately, keeping procurement straightforward and avoiding delays tied to proprietary hardware.
