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.

Flush weldable deck sockets (single, double and quad) for tweendeck applications; DNV-GL approved; SWL 250 kN tension / 210 kN shear (MBL 500 kN / 420 kN).
No prices online — quotations are prepared per application and quantity, usually within one business day; a more involved enquiry may take a little longer.

Load ratings are as published in the TLA 2026 catalogue. Site-specific ratings and certification: on request.
Tweendeck container securing; naval and commercial shipping applications.
Where a raised socket cannot be used — most commonly a ship's tweendeck — the flush deck socket welds in level with the surrounding plate instead of standing proud. Supplied in four configurations — single, double side-by-side, double end-to-end and quad, each carrying its own SKU — with a top-plate thickness of 16 mm or 28 mm matched to the tank-top thickness, standard pitches of 203/365/258 mm (others on request), and DNV-GL class approval. Every unit is tightness tested before dispatch.

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.
