Space-constrained container securing where containers are already placed directly adjacent; marine and shore stacking applications.
Designed for locations where there is no working space beside the container — typically because an adjacent container is already in place — the breech twistlock locks from below rather than from the side. It is available in left- or right-locking configuration and is always used with its matching breech base: a round foundation plate, welded or cast into the deck, slab or steel structure, that the twistlock engages from underneath. The base carries its own SKU and is ordered alongside the twistlock, one per securing point.

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.
