Hand tool for crimping MC4 solar connector terminals to 1.5 - 6.0mm² cable.

This tool features a ratchet mechanism with an automatic spring return when the crimp is completed. This provides a controllable crimp cycle and ensures that the jaws of the tool are not released until a full crimp has been applied to the terminal. 

The jaw positions are marked for different cable sizes, the crimp pressure is adjustable via a notched dial on the ratchet mechanism and a ratchet release lever allows you to open the jaws part-way through a crimp cycle.

Further information

The front and middle jaw positions are for open-barrel MC4 terminals (1.5 - 2.5mm² and 4.0 - 6.0mm² respectively) where a 'rolled' crimp is required.  The rear jaw position is for closed-barrel MC4 terminals where an 'indent' crimp is required.
