Our customers say...

This wiring appears to be almost perfect for it's intended use. The blue outer layer is limp yet tough, the wire itself is tinned as it should be. The size is quite large though, coming in at .625+ depending on how round you can keep it. I'm stuffing it into a 6 pin connection and it is tight, maybe watertight if I'm lucky.

Polar Wire Customer on Multiconductor Trailer Cable
Quality of this wire is above anything that I have seen in the past. Would definitely purchase wire or cable again through Polar.
Daniel
Polar Wire Customer on Twin Trailer Cable
It has been very difficult to source products suitable for our forestry business in northern MN where temps in winter require power cable that can remain reasonably flexible in below zero temps...Then you do your internet research and find Polar Wire, guess what? Problem solved—quality product!! Works EXACTLY as advertised—flexible, durable wire that works in cold temps—DONE!
