MiTek Z4 Tie-Down System
The MiTek Z4 Tie-Down System provides the building industry with a simple, efficient, quality tie-down system with unparalleled customer service. The MiTek Tie-Down System is used in multi-story buildings to transfer uplift tension forces that result from earthquake and wind loading, to the foundation. The CNX Cinch Nut allows for easy, fast, and dependable one-step installation. MiTek Z4 Tie-Down Runs are engineered for maximum material and labor efficiency to provide the most economical system in the industry.
The CNX Cinch Nut is a shrinkage take-up device that is evaluated under the IBC and the City of Los Angeles building codes and is accepted by building departments nation-wide. The CNX ability to perpetually “travel” down the length of the threaded rod allows it to compensate for natural shrinkage and settlement that occurs in wood buildings, therefore keeping connections of Tie-Down Runs tight to the floor framing members for the life of the building.
The MiTek Z4 Tie-Down System with the CNX Cinch Nut is designed to limit story drifts of multi-story buildings and eliminate additional structural damage caused by loose connections in the floor framing. The system was designed following the Northridge Earthquake when the effects of wood shrinkage, building settlement, and other building deformation were shown to be factors contributing to damage.
The MiTek Z4 design was the first in the industry to provide a continuous load path for uplift that perpetually adjusts its connections to the floor system as the building deforms. The MiTek Z4 Tie-Down System is engineered, tested, and code evaluated to perform. It continues to be an innovative leader in the multi-story building industry.
