Dynamic load metal buckles are safe and effective in shipping static and dynamic loads quickly and easily. The cargo can be secured by combining the Metal Buckles with the polyester lashings, which, when in motion, provide safety and security during transportation. The flat-stamped metal buckle is an excellent and inexpensive alternative to forged and welded metal buckles. Flat-stamped metal buckles, which can hold 2 to 3 tons, are sufficient in many applications, especially inside containers.
