Ship decks; temporary container placements (control rooms, modular buildings); repeated installation/removal applications without a permanent twistlock.
A weldable socket that pairs with the dovetail twistlock, so a container can be set down and lifted off the same point repeatedly without leaving a twistlock permanently in place. The setout drawing alongside gives the pitches for the single and the double transversal arrangement, together with the weld preparation for the 45° and 55° faces.

Forged D-ring welded to a dovetail plate that slides into a dovetail slipper, giving a rated, removable lashing point wherever a slipper is already installed.

ABD-D1 bolted-on dovetail twistlock — a single-casting chassis on a 16 mm base plate that bolts to a concrete foundation or steel structure, securing a container with no permanent modification to the container itself.

Dovetail twistlock welded to a 200 x 200 x 16 mm base plate — the standard fabricated boltable, and the starting point for any bolt pattern, footprint or mounting arrangement a site requires.
