The Lift for the Jobo CPP-2 and CPA-2 Processors is used to provide lab-quality processing of film and prints.
The Lift makes these processors easier to use, but it's not required to use the processors (except when using the Expert drums).
The Lift incorporates a transfer-gear that connects to the cog gear on the tank.
These CPP-2 & CPA-2 processors are designed for advanced amateurs and small labs.
