VERSA-LOK’s unique hole-to-slot pinning allows variable bond, which is a structurally preferable installation method. Variable bond eliminates the gaps between units that are necessary with wall systems that require exact half-bond installation. The hole-to-slot pinning system allows units to be adjusted horizontally as needed during construction, and it allows vertical joints to wander in relation to joints in courses above and below.
VERSA-Tuff Pins
In VERSA-LOK’s unique system, pins are inserted in the holes of an upper unit and tapped into receiving slots of two lower units. Top-pinning makes installation easy because the units do not have to be lowered onto pins. Instead, pins are placed in units after the units are set near their final position.
