Standard Nuheat mats come with a 10 ft long factory attached power lead. Custom mats can be created with leads up to 22ft in length.
However, we also carry Nuheat lead extension kits that can extend the lead on a Nuheat mat or cable an extra 10ft. If you need less than 10ft, cut the existing lead short and splice the extra 10ft onto it using the extension kit. Never cut or shorten the extension.
