Insulating Battery Boots are a neat way to insulate battery connections for safety and appearance. This flexible black boot is molded to fit over our Top Post Battery Terminal (Part No. 4150, sold separately), but it can be used to insulate most other types of battery connections as well.
Boots must be slipped over the cable before the terminal is attached. This boot is a snug fit on 4 gauge battery cable (about .36" OD). It is flexible enough to fold back for charger or jumper cable access.
