A double drum lock is the perfect solution to keeping the contents of drums safe and secure. This plastic double drum lock is a simple design that utilizes the bungs of the drum to position threaded cylinders for lockout. Once the cylinder lockouts are tightened and in the correct position a rod can then be inserted through one of the port holes of both cylinders. The rod design has an open ended frame for allowing padlock to pass through for complete lockout. Padlock not included.
