MFG5B

Description:
Introducing the Rockville MFG5B 4 AWG Tinned OFC 5ft Ground Wire – the go-to solution for marine, car audio, and solar power setups that demand reliability and performance. As a proud American brand, Rockville crafts this wire with precision, backed by our USA-based audio engineers who ensure top-tier quality. Featuring a true 4 AWG gauge with 1,862 strands of 0.12mm tinned oxygen-free copper (OFC), this cable delivers exceptional conductivity and durability. Wrapped in heavy-duty marine-grade PVC, it’s saltwater-proof, moisture-proof, and built to withstand heat, cold, oil, gas, and fumes—making it a must-have for boats, cars, or solar installations.
- True 4 AWG Gauge: Engineered for high-power applications, this wire minimizes voltage drop and maximizes current flow, perfect for robust audio systems or solar setups.
- Pre-Installed Ring Terminal with Grounding Bolt Kit: Comes ready-to-install with a pre-attached 5/16" ring terminal, black heat shrink, and a rust-resistant grounding kit (washer, bolt, and nut)—no extra tools or parts needed for a secure, hassle-free connection.
- Bonus Heat Shrinks & Ferrules: Includes 4 heat shrinks and 4 ferrules so you can cut to length and finish with clean, professional-grade terminations every time.
- Black Mesh Split Loom: Keeps your setup neat, protected, and tangle-free—unlike bare wires that fray and clutter your install.
- Rustproof Tinned OFC: 100% tinned copper resists rust and oxidation, ensuring long-lasting performance in harsh marine or automotive environments.
- Flexible Marine-Grade PVC: The heavy-duty jacket is waterproof, flexible, and easy to route through tight spaces, saving you time and frustration during installation.
- Max Load Capacity: Handles up to 150A at 20 feet, delivering the power your system craves without breaking a sweat.
Upgrade your grounding game with Rockville’s MFG5B—built tough, tinned for longevity, and packed with everything you need for a pro-level install. Whether you’re wiring a boat, car stereo, or solar array, this kit’s got you covered.
