Domino Clamps allow you to attach almost anything to shipping containers. They are strong, safe, easy to use and above all; they will not damage your container. They attach directly into the side or end holes of the corner casting, firmly attaching a 20mm thick steel plate with four M1 threaded holes, ready to bolt on whatever you need. They are rated to 2000kg in vertical shear, and are removable and reusable so you can use them again and again.
