Domino clamps
Quick-connect mounting clamps that lock into any ISO corner casting using a single 10 mm hex key, presenting four M12 tapped mounting holes for attaching accessories, structures or equipment — no welding, no drilling, fully reusable.

Steel mounting brackets that engage the top corner casting aperture without drilling or welding, providing a threaded socket for masts, poles, antennas, security cameras and conduit runs on shipping containers; two configurations available.
No prices online — quotations are prepared per application and quantity, usually within one business day; a more involved enquiry may take a little longer.
| Material | Mild steel plate (6 mm min.), welded construction |
|---|---|
| Finish / Coating | Black powder-coat (standard); other finishes on request |
| Standard | ISO 1161 corner casting interface |
| Load Rating | Confirmed per application — depends on the mounted equipment and its offset |
Load ratings are as published in the TLA 2026 catalogue. Site-specific ratings and certification: on request.
Security camera masts; solar panel and solar-light mounting poles; antenna and aerial bases; conduit routing; flag and signage poles on container structures.
Uses the existing ISO 1161 top corner casting oval aperture to create a secure, removable mounting point with no drilling or welding. The 9.1 pole/mast configuration is a welded 6 mm steel body with an integrated 1½" NPT coupling for a custom-length mast or pole, tightened with a single bolt in under five minutes. The 9.2 platform/rail configuration is a low-profile bracket that seats over the aperture and accepts standard rail or platform attachments. Both fit any standard ISO 20 ft or 40 ft container. A mast extending past the container edge loads the bracket eccentrically, and the moment grows with mast length and wind area — so capacity is confirmed per application rather than quoted as one figure.

Mounting-face detail of the Domino Clamp — the four M12 tapped holes and clamp jaw that engage the corner casting's shield or stadium hole, including when a twistlock is already occupying the corner.

Horizontal twistlock with a flanged end plate — locks into the side aperture of an ISO 1161 corner casting and gives four M12 tapped holes for fixing walkways, roofs, masts, staircases and accessories to the container.

Horizontal twistlock with an articulating D-ring — locks into the side aperture of an ISO 1161 corner casting to anchor lashing, guy lines and rigging. Rated in tension; not a lifting point.
