Durable and reliable construction Made of durable materials for strength and long service life. Designed to hold heavy-gauge wiring securely and provide consistent electrical contact over time. Clear 2-way distribution for power and ground One input hole and two output holes let you split a single feed cleanly into two circuits. Input accepts 0, 2, or 4 AWG cable; outputs accept 4, 6, or 8 AWG cable sizes, supporting a range of common automotive and battery wiring setups. Corrosion-resistant protection Includes an attachable plastic cover made of industrial material to protect contacts from water and dust. The cover reduces exposure and helps prevent corrosion for more stable long-term power distribution. Easy, safe installation Insert wires and tighten the large adjusting screws to clamp conductors securely. The screws provide firm mechanical retention while the block’s good conductivity maintains reliable power transfer. Why customers need this Simplifies splitting heavy-gauge power or ground lines without soldering or bulky connectors. Prevents loose or messy connections that cause voltage drop, intermittent power, or heat buildup. Provides a compact, protected junction point that improves durability in demanding environments. Typical applications Car and truck electrical systems: cleanly split battery power to amplifiers, starters, or accessories. Marine and RV installations: route battery feeds to multiple circuits while protecting contacts from moisture and contaminants. Off-grid battery and inverter systems: organize and distribute heavy-gauge battery cables for inverters, charge controllers, and loads.
