The set includes two straps of each length (10, 15 and 20 inches), giving you enough options to replace worn straps or set up multiple grounding points. The flat 1\/2-inch braid and plated 5\/16-inch mounting holes make them straightforward to fit in most automotive, marine, or off-road electrical systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these straps improve vehicle electrical performance?\u003c\/h3\u003e\n\u003cp\u003eGood grounding reduces electrical resistance between engine and chassis components, stabilizing sensors and accessory operation.
