The Simpson CBH2.37X7.63B-KT Concealed Glulam Joist-to-Beam Hanger is engineered specifically for glulam construction where computer modeling and CNC manufacturing deliver beams to the jobsite in precise lengths with preinstalled concealed hangers. Installed using readily available Strong-Drive SDS Heavy-Duty Connector screws (included in the kit), this 3-gauge steel concealed beam hanger delivers a clean, hidden connection that satisfies both architectural and structural demands. It has been tested for inter-story drift performance and has achieved 1-hr and 2-hr fire resistance ratings according to ASTM E119, making it a reliable choice for demanding residential and commercial glulam assemblies.

Key Features

• Concealed design for aesthetics and fire-rated performance - keeps the connection hidden from view while meeting 1-hr and 2-hr fire resistance ratings per ASTM E119, so finished spaces look clean and comply with fire-rated assembly requirements.
• +/- 1/32-in. beam length tolerance on each end - accommodates minor variations in beam length delivered to the jobsite, reducing the need for field adjustments and speeding up installation.
• Multiple router options to suit jobsite needs - gives installers flexibility to match the routing method that best fits their equipment and workflow on-site.
• Inter-story drift performance tested to over 2% - confirms the connection can handle lateral movement in multi-story structures, providing confidence in structural integrity under real-world loading conditions.
• Code-listed per ICC-ESR-2552 - provides the documentation needed for inspections and project approvals, reducing delays on permitted work.
• Made from 3-gauge steel with an electrogalvanized finish - heavy-gauge construction delivers robust load capacity, and the electrogalvanized coating provides corrosion resistance for long-term durability.
• Two backplates make up one connection, with all fasteners included - the kit includes both backplates plus 18 Strong-Drive SDS25300 screws and 18 Strong-Drive SDS25600 screws, so installers have everything needed for a complete connection right out of the box.

Why This Product

• Built for modern glulam workflows - designed specifically to work with CNC-manufactured glulam beams delivered with preinstalled hangers, this concealed hanger slots directly into precision-built assemblies without requiring extra field fabrication.
• Dual fire resistance ratings open more project types - achieving both 1-hr and 2-hr ratings per ASTM E119 means this hanger qualifies for a broader range of fire-rated construction assemblies, giving specifiers and contractors greater flexibility across project types.
• A complete, code-backed connection in one kit - with two backplates and all required Simpson Strong-Drive screws included, and the connection code-listed per ICC-ESR-2552, contractors get a fully documented, inspection-ready solution without sourcing additional hardware separately.
• Structural confidence in lateral-load applications - inter-story drift performance tested to over 2% means the hanger is validated for use in structures where lateral movement is a design consideration, supporting engineer and inspector confidence on multi-story glulam projects.
