Cube 58mm Cap Spanner
This durable cap spanner is the ideal tool for opening up our 20L cubes. Use it to quickly and easily open up the tamper evident 58mm caps. Provides plenty of torque to easily shear off the locking ring as you open the cap. Eliminates all the hard work. Reduces stress and strain.
The rectangular key at the base of the handle fits the keyways in the bungs at the bottom of the cubes. So you can also use this spanner to get the bungs out of the cubes. Please note that to minimise the risk of leaks, we use cubes without a perforation in the bung opening. If you wish to use the bottom bung to dispense contents you will need to drill out the backing behind the bung. Alternatively, consider ordering a Tap in a Cap so you can flip the cube on it's side and dispense through the 58mm opening.
