JORDAHL® Toothed Straps

JORDAHL toothed straps JVB-V and JVB-N are excellent product choices when connecting precast concrete elements such as columns and walls with each other.   

In combination with JORDAHL® anchor channels and T-bolts, they form an ideal fastening system for the efficient alignment of precast elements in a 3D space. Installation is easy, and the adjustable connections compensate for the manufacturing and placement tolerances of the concrete components.

JORDAHL® toothed straps also support high loads in two directions, while a sliding connection to the JORDAHL® anchor channel allows vital differential movement between components in the third dimension. The software allows load bearing capacities to be verified analytically with accuracy. Consequently, the combined system represents a powerful, cost-effective and completely verifiable alternative to conventional connections.
