FR-72DQ Raised double ISO foundation one elongated hole
The CONTECH® raised ISO deck socket with one elongated hole gets welded on top the deck of the vessel. The standard height is 110mm, and is also available with a non standard height up to 160mm. Those foundations are used with ISO bottom twistlocks as the wide body manual twistlock T-2 or the semiautomatic wide body twistlock T-5/SB, to secure the containers to the deck of the vessel. The elongated hole is standard 185mm and allows additional sliding necessary to compensate for shifts between the hatch cover and the external stanchions. The standard distances between the center points are 203, 216 and 258mm (other distances on request). It can also be used in combination with a turn foot d-ring type LE-3 or various kinds of twistlocks.
