The Bishop Bolt system is a yielding passive support system that is grouted prior to installation. The two pairs of double paddles act as anchors once the unit is grouted. The unit de-bonds during loading and elongation of the steel occurs between the two sets of paddles resulting in engineered yieldability.
The Bishop Bolt can be supplied with 16mm, 18mm or 20mm bar depending on requirements. The unit has an elongation of 23% in static conditions and 15% under dynamic loading.
