Due to the use of an innovative dual self-locking system, our product does not require you to use any additional tools, including a scaffolding spanner. This means that work becomes more efficient – faster and safer. Professionals have approved through lifting tests that the Crab Clamp allows you to easily adjust its width to fit up to ten sheets – 40% more than any other similar product available on the market. The Crab Clamp only needs two operators at a time, meaning that no time is wasted and labour costs are reduced.
