Simpson ACBH Concealed Beam Hanger is a high-capacity aluminum connector engineered specifically for the demands of mass timber, glulam, and cross-laminated timber construction. Machined from aluminum for exceptional strength, this concealed end-grain beam hanger delivers an allowable stress design load capacity of up to 20 kips - making it the strongest connector in the Simpson Strong-Tie line of concealed end-grain beam hangers. The fully hidden connection preserves a clean wood-only aesthetic while meeting one- and two-hour fire resistance ratings per ASTM E119, making it an ideal choice for fire-rated structural assemblies in new construction.

Key Features

• Machined aluminum construction - delivers a high-capacity, lightweight connector that withstands the structural loads demanded by mass timber and engineered wood framing
• Up to 20-kip allowable stress design load capacity - the highest load rating in the Simpson Strong-Tie concealed end-grain beam hanger family, giving engineers and builders confidence in heavy structural applications
• Concealed connection design - hardware is hidden from view, preserving a wood-only aesthetic suited for exposed timber interiors and architectural applications
• One- and two-hour fire resistance ratings per ASTM E119 - meets code requirements for fire-rated assemblies without sacrificing structural performance
• Factory installation using Strong-Drive SDCF Timber-CF structural screws - enables precise, controlled installation in prefabrication settings for better quality control and faster onsite erection
• Generous onsite fit-up tolerance - allows smooth, easy beam placement in the field, reducing labor time and minimizing fit-up complications during installation
• Manufactured and stocked in the United States - supports reliable product availability for project scheduling
• Aluminum finish - inherently resistant to corrosion, suited for interior structural connections in engineered wood and mass timber assemblies

Why This Product

• Strongest concealed hanger in the Simpson Strong-Tie lineup - with a 20-kip allowable stress design load, this connector handles the heaviest beam-to-beam and structural framing loads in mass timber and glulam systems where standard hangers fall short.
• Built for prefabrication and modular timber construction - factory installation with Strong-Drive SDCF screws means the hanger can be pre-installed before delivery, speeding up onsite assembly and reducing field labor costs.
• Code-compliant for fire-rated construction - one- and two-hour ASTM E119 fire resistance ratings mean this hanger can be specified in fire-rated floor and roof assemblies without requiring additional protective measures on the connector itself.
• Clean aesthetic for architectural exposed timber - the fully concealed design keeps structural hardware out of sight, making it a natural fit for exposed glulam, structural composite lumber, and mass timber interiors where appearance matters.

Frequently Asked Questions

What is the load capacity of the ACBH Concealed Beam Hanger?

The ACBH has an allowable stress design load capacity of up to 20 kips, making it the strongest connector in the Simpson Strong-Tie line of concealed end-grain beam hangers. This capacity makes it well suited for heavy structural loads in mass timber, glulam, and engineered wood framing applications.

Does this hanger qualify for fire-rated assemblies?

Yes. The ACBH Concealed Beam Hanger carries one- and two-hour fire resistance ratings per ASTM E119, allowing it to be used in fire-rated floor and roof assemblies in new construction projects where code compliance is required.

What fasteners are required to install the ACBH, and are they included?

Installation requires Strong-Drive SDCF Timber-CF fully threaded structural screws. These screws are not included with the hanger and must be purchased separately. The hanger is designed for factory installation using these screws prior to onsite beam erection.

What types of wood products is the ACBH Concealed Beam Hanger compatible with?

The ACBH is designed for use with a wide range of engineered and structural wood products, including glulam beams, mass timber and cross-laminated timber (CLT) members, structural composite lumber, and general engineered wood framing applications.
