Dovetail twistlock
Weldable dovetail twistlock for securing containers to structures or structures to containers; available in 45° and 55° configurations, left-hand (standard) and right-hand options.

A raised ISO deck socket on a drilled base plate — bolts down to a slab or footing instead of being welded to steel, and lifts the container clear of the ground on the same casting used elsewhere in this section.

Anchoring containers to concrete slabs, footings and prepared ground; modified containers needing services routed underneath; keeping a container clear of standing water.
Where the raised deck socket on the preceding page is welded to a steel deck, this one arrives on a drilled plate and bolts down — which is what a concrete slab or a footing actually needs. The socket itself is the same casting, so the twistlock range that fits one fits the other, and it comes as a single or a double. The 160 mm of clearance is measured to the underside of the container with the twistlock in place — the room to run a waste line, and the gap that keeps a floor out of standing water.

Weldable dovetail twistlock for securing containers to structures or structures to containers; available in 45° and 55° configurations, left-hand (standard) and right-hand options.

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.

Weldable dovetail slipper (45° and 55°, single and double) providing a permanent socket for matching dovetail twistlocks, allowing containers to be repeatedly mounted and removed without a permanent twistlock.

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.
