The Simpson CBH Concealed Glulam Beam Hanger is engineered for modern glulam framing systems where computer modeling and CNC manufacturing deliver beams to the jobsite in precise lengths with concealed hangers already installed. Designed specifically for these applications, this hanger installs using readily available Strong-Drive SDS Heavy-Duty Connector screws and provides a fully hidden connection that satisfies both architectural finish requirements and fire-rated assembly standards. Built from heavy-duty 3-gauge steel with a hot-dip galvanized finish, it is well suited for exterior and treated-wood environments where corrosion resistance is essential. Each kit includes two backplates that together make up one complete connection.

Key Features

• Concealed hanger design - keeps structural hardware out of sight, preserving clean architectural aesthetics without sacrificing structural performance
• 1-hr and 2-hr fire resistance ratings per ASTM E119 - qualifies this hanger for fire-rated floor and roof assemblies, reducing the need for additional protective measures
• Inter-story drift performance tested to over 2% - confirms the connection can handle lateral movement demands common in multi-story construction
• +/- 1/32-in. beam length tolerance on each end - accommodates minor length variations in prefabricated glulam members so installation stays on schedule
• Multiple router options - gives installers the flexibility to match jobsite conditions and preferred cutting methods
• Code-listed per ICC-ESR-2552 - simplifies plan approval and inspection since compliance with recognized evaluation standards is already documented
• 3-gauge steel with hot-dip galvanization (HDG) - delivers extra corrosion resistance for exterior installations and applications involving treated wood, extending the service life of the connection
• Two-backplate connection system - each kit contains the complete pair of backplates needed for one full connection, so components are always matched and ready to install

Why This Product

• Built for prefabricated glulam construction - the CBH concealed beam hanger is specifically designed to work with CNC-cut glulam members delivered with pre-installed hardware, making it a natural fit for engineered wood framing workflows rather than a generic adapter
• Dual fire ratings give projects more design flexibility - achieving both 1-hr and 2-hr fire resistance ratings per ASTM E119 means this single hanger model can satisfy a wider range of code-required assembly types without substituting a different product
• HDG coating addresses the most demanding installation environments - the hot-dip galvanized finish goes beyond standard coatings to protect against corrosion in exterior conditions and where pressure-treated lumber is used, making this hanger a dependable long-term choice
• Concealment supports both aesthetics and compliance - hiding the connection hardware benefits exposed-beam architectural applications while simultaneously contributing to the tested fire resistance performance, so builders do not have to choose between appearance and code compliance
