Drum lock ring is a reliable sealing component for open head steel drum, open head plastic drum and fibre drum. It seals the drum lid and drum body by hooping them together. Drum locking rings usually vary in diameter, thickness, cross section design and closing components (drum clamp or drum bolt). Surface of the drum lock ring is galvanized, and it is able to protect contents in drum even under strict storage condtion.
To reach sealing property, the diameter and shape of cross section needs to fit the drum lid perfectly. Drums with bigger volume usually require drum lock ring with thicker thickness. Drum lock ring with bolt could provide stronger sealing force, but need wrench to close or open it. Drum lock ring with clamp is more flexible, and it is more convinient for operating.
