The Simpson Strong-Tie ACBH3X15.37-KT is a concealed beam hanger kit engineered for the demands of mass timber construction. Machined from aluminum, this high-capacity connector delivers an allowable stress design (ASD) load capacity of up to 20 kips - making it the strongest connector in the Simpson Strong-Tie line of concealed end-grain beam hangers. Measuring 3 in. wide by 15-3/8 in. tall, the ACBH features a fully concealed connection that preserves a clean, wood-only aesthetic while simultaneously achieving one- and two-hour fire resistance ratings per ASTM E119. Factory installation is streamlined using the included fully threaded Strong-Drive SDCF Timber-CF structural screws, and a generous onsite fit-up tolerance ensures smooth, efficient beam placement. Manufactured and stocked in the United States, the ACBH3X15.37-KT kit includes (2) backplates forming one complete connection along with (48) Strong-Drive SDCF22614 screws - everything needed for a single, fully concealed beam connection.
