Many US cars have top screw in or MAINLY Side cable Screw in Battery Positive and Negative terminals.... which can be a PAIN in the butt most times. This allows if you have the option to keep the screw in battery and screw these post terminals in.

Mainly on 1982 & newer US Cars.

Supplies as shown.. one pair.

NOTE TOO.. if keeping your factory screw type cables but wanting to use POST connectors.. see and grab a set of cable converters here # PW87004 - per below
