This telescopic container twist lock is specially designed for skeleton semi-trailers. The plum blossom five-petal base provides large contact area and uniform stress distribution, resisting deformation under heavy load. The double-layer telescopic sleeve allows height adjustment to fit all standard 20ft/40ft containers. Made of thick cast steel, the lock head delivers tight locking without loosening. With double anti-rust treatment of paint and galvanization, it withstands rain and grit erosion. It works stably under long-term heavy-duty transport, firmly fixing containers to avoid sliding or falling and fully secure transportation safety.
