The Simpson Strong-Tie HCJTZ Concealed Joist Tie with Pins is a heavy concealed beam tie engineered for use with large glulam beams resisting heavy loads. Featuring a unique profile, the HCJTZ allows installers to insert the connector directly into the end of the beam without requiring a visible slot cut into the bottom of the beam - delivering a clean, finished appearance without sacrificing structural performance. The HCJTZ is part of a complete concealed connector system that includes the CPTZ and CBTZ, offering a cohesive solution for demanding timber framing applications.
