Insulating Battery Boots are a neat way to insulate battery connections for safety and appearance. This flexible Red boot is molded to fit our Top Post Battery Terminal (Part No. 4150), but it can be used with most other types of battery connections as well.
The boot must be slipped over the battery cable before attaching the terminal to the cable. The opening is a snug fit on 4 gauge battery cable (about .36" OD). The flexible boot can be folded back to connect charger or jumper cables to the battery terminals.
