Stable performance: Durable brass stud terminals prevent short circuits and allow power to pass safely through a firewall or panel. Robust materials: Rubber, zinc alloy, and brass construction resist rust and provide strength for longterm reliability. Friction reduction and strain relief: Large cables can rub on edges; this connector minimizes friction and delivers strong strain relief for the lead. Wide compatibility: Designed for automotive, caravan, boat, yacht, racing car, and agricultural vehicle power systems; fits standard battery cables. Practical use scenarios: 1) In a car, route power from the battery through the firewall to the fuse box. 2) On a boat, feed power from the battery cabinet to the electrical panel. 3) In a caravan, connect solar or generator lines to the house battery distribution.
