Designed to provide a concealed connection for fire performance and architectural aesthetics, the ACBH from Simpson Strong-Tie joins the existing CBH concealed beam hanger as part of a family of innovative connectors and solutions for mass timber construction. Fabricated from machined aluminum, the ACBH allows for the use of 45º countersunk fasteners, delivering significantly higher loads and stiffness per screw. For situations where a single ACBH is still not sufficient for the design loads, two connectors can be used on a single beam end to achieve twice the allowable download of a single connector.
