FT12 Standard Coupler

The nVent LENTON Ultimate FT12 Standard Coupler is designed for high performance applications, efficiently creating mechanical reinforcing bar connections where the second bar can be rotated and is not restricted in its axial direction. The nVent LENTON self-aligning, taper-thread reduces misalignment issues and helps eliminate cross-threading during installation. The FT12 is used in conjunction with the MT12 Male Taper-Threaded Stud for bar-to-bar connections.

Additionally, the FT12 Standard Coupler can be used in conjunction with threaded bars produced on nVent LENTON threaders. However, when using in conjunction with taper-threaded bars produced on nVent LENTON threaders, the performance of the connection may change. Contact your nVent LENTON representative for more information.
