The Simpson CBH Concealed Glulam Beam Hanger is engineered for modern timber framing projects where computer modeling and CNC manufacturing allow glulam beams to arrive at the jobsite in precise lengths with hangers preinstalled. Sized for a 2-3/8 in. wide by 7-5/8 in. tall glulam beam, this heavy 3-gauge steel hanger carries a hot-dip galvanized finish that makes it a reliable choice for exterior assemblies and treated-wood applications. Installed using readily available Strong-Drive SDS Heavy-Duty Connector screws, the CBH supports both joist-to-beam and joist-to-column connections while keeping all hardware fully concealed for a clean architectural result. With tested fire resistance ratings and inter-story drift performance, it delivers the structural confidence required in today's code-compliant, exposed-timber construction.

Key Features

• Concealed hanger profile - keeps all hardware hidden from view, meeting the aesthetic demands of architecturally exposed structural framing without sacrificing structural integrity
• 1-hr and 2-hr fire resistance ratings per ASTM E119 - qualifies this hanger for use in fire-rated structural assemblies, reducing the need for additional fire-protection measures on the connection
• Inter-story drift performance tested to over 2% - provides confidence in seismic and lateral-load applications where connection flexibility under movement matters
• +/- 1/32 in. beam length tolerance on each end - accommodates minor dimensional variation in CNC-cut glulam, making field installation faster and reducing the chance of costly fit-up issues
• Multiple router options to suit jobsite needs - gives contractors flexibility in how the slot is cut, adapting to the tools and workflow already on site
• 3-gauge steel with hot-dip galvanization - delivers heavy-duty corrosion resistance suited for exterior installations and assemblies involving pressure-treated wood
• Two-backplate system makes one complete connection - the kit includes both backplates so the full connection is accounted for in a single purchase, simplifying procurement
• Code-listed per ICC-ESR-2552 - supports plan approval and inspection sign-off by providing a recognized third-party evaluation for building officials and engineers

Why This Product

• Built for prefabricated glulam construction - the CBH is specifically designed to work with CNC-manufactured glulam beams that arrive with hangers preinstalled, streamlining the connection process and reducing on-site labor compared to field-fabricated alternatives
• Dual fire ratings open more project types - achieving both 1-hour and 2-hour fire resistance ratings per ASTM E119 means one hanger model can satisfy a wider range of fire-rated assembly requirements, giving specifiers a single solution across multiple project conditions
• Concealed design serves both form and function - the hidden hardware profile satisfies architects specifying exposed timber aesthetics while simultaneously contributing to fire-rated performance, eliminating the tradeoff between appearance and code compliance
• HDG finish extends service life in demanding environments - the hot-dip galvanized coating provides a higher level of corrosion resistance than standard finishes, making this hanger a dependable long-term choice in exterior framing and treated-wood applications where moisture exposure is a concern

Frequently Asked Questions

What screws are required to install the CBH2.37X7.63H-KT?

For a joist-to-beam application, install with (18) Strong-Drive SDS25300 screws and (18) Strong-Drive SDS25600 screws. For a joist-to-column application, use (36) Strong-Drive SDS25600 screws. Note that screws are not included with the hanger kit - the package contains only the two backplates that make up one complete connection.

What fire resistance ratings does this concealed hanger carry?

The CBH2.37X7.63H-KT has achieved both 1-hour and 2-hour fire resistance ratings per ASTM E119, making it suitable for exposed and fire-rated structural assemblies. It is also code-listed per ICC-ESR-2552.

Why is this hanger recommended for exterior or treated-wood applications?

This hanger is fabricated from heavy 3-gauge steel with a hot-dip galvanized (HDG) finish, which provides extra corrosion resistance compared to standard coatings. This makes it well suited for exterior environments and applications involving treated lumber where moisture or chemical exposure is a concern.

What beam size is this hanger designed to fit, and does it allow for any installation tolerance?

The CBH2.37X7.63H-KT is designed for a beam that is 2-3/8 in. wide by 7-5/8 in. tall. It also features a +/- 1/32-in. beam length tolerance on each end, which helps simplify installation when working with glulam beams delivered to precise lengths with the hangers preinstalled.
