Computer modeling and CNC manufacturing enables glulam to be delivered to the jobsite in precise lengths and with preinstalled concealed hangers. The Simpson Strong-Tie CBH Concealed Glulam Beam Hanger (Model CBH2.37X7.63H-KT) is specifically designed for such applications, and is installed with readily available Strong-Drive SDS Heavy-Duty Connector screws. Fabricated from heavy 3-gauge steel with a hot-dip galvanized (HDG) finish for superior corrosion resistance, this hanger fits a 2-3/8 in. wide by 7-5/8 in. tall beam and delivers both architectural appeal and code-compliant fire-rated performance. The CBH 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 trusted solution for exposed and fire-rated structural assemblies.

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.
