The 12-375 is a plug-to-plug cable and clamps set for convenient, cost effective jump starting. This kit contains a 5-foot battery lead cable with a plug, and a jumper cable with a plug and 400 amp clamps. Jumper cables are 15-foot long for easy access to the disabled vehicle, and constructed of 4-gauge welding cable. The plugs are non-reversible to ensure correct polarity when connecting the jumper and battery lead cables. This set is appropriate for light to medium duty jump starting.
