The package bundles a length of pure copper cable, ten tin-coated copper lugs in two stud sizes, and 3 ft of black heat shrink tubing, saving time compared with sourcing parts separately. The single biggest reason to buy is the combination of genuine annealed copper strands and a tough EPDM jacket that makes routing and repeated bending much easier for battery, welding or marine power runs.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePure copper construction:\u003c\/strong\u003e The annealed copper strands follow ASTM standards and deliver excellent conductivity for battery and welding applications. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra flexible jacket:\u003c\/strong\u003e EPDM insulation is solvent resistant and allows tight radius bends for installation in cramped spaces. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector kit included:\u003c\/strong\u003e Five 5\/16' and five 3\/8' tin-coated copper lugs are supplied so users can terminate cables for common stud sizes without extra purchases. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutdoor durability:\u003c\/strong\u003e Lugs have a closed-end design and tin coating for corrosion protection in marine or exposed environments. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat shrink protection:\u003c\/strong\u003e 3 ft of black polyolefin tubing rated to -55 to +125 Celsius provides environmental and strain relief protection where needed. \u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis kit suits installers, small fabrication shops, mobile welders and boat owners who need a long, flexible battery or welding lead that can be routed through tight spaces and connected to common stud sizes.
