This is a set of large-capacity plastic drum molds specially crafted for bulk material storage, food processing, and the environmental sanitation industry. The distinct prominent feature of the mold is the robust black external locking clips equipped on both sides of the barrel. When the lid is closed, these clips firmly lock it in place, ensuring it never loosens or leaks during handling, dumping, or stacking. The barrel body features reinforced vertical pillars to maintain structural rigidity under large capacity loads.
