The Duplock drum security seal is an effective, two piece, security seal for drum lid spring clamps. Our standard, ex-stock Duplock is sequentially numbered, however the seal can be customised with logo or other wording according to customer requirements. 

Duplock is easily sealed by pushing the spigot and through the spring clamp eyelet and locking the seal head in place to secure the drum. It is removable by hand with a firm twisting movement.

Ex-stock delivery can normally be made next working day for customer account holders or customers paying by credit card.
