Couplings to connect the two shredder's shafts together at their ends for the purpose of transmitting power between the motor and blade box.
(Screws not included!)
Its a basic way to connect the motor to the hex-bar using welding. while still being able to take them apart later by disassembling the screws
The couplings module was not part of version 2 of the shredder. It's an add-on we've designed to fit our needs.
