The Dayton Superior T42 Double Ground Release II System consists of two T41 Ground Release II Inserts, two T43L Ground Release II Hardware units and a T46 Ground Release II Spreader Beam with twin 8-1/2 ton shackles. The two inserts are spaced on 12” centers to mate with the tandem hardware attached to the spreader beam. After lifting and positioning the panel, the hardware is released from the ground in the same manner as the basic system.
