A module designed to trim the carbon tank. It fits inside the cylinder boot, and its weight is tailored to the size of the tank.

It works perfectly when the cylinder contains a light gas, which can cause the bottom of the tank to float upwards.

The weight is cast from lead and coated with a layer of plastic.
Thanks to the plastic coating, it won’t scratch other equipment, has no sharp edges, and most importantly is safe for both humans and animals.
