It's long, It's tough to judge 120' until it's in your hands. For the cost it is well worth it. I'm forced to live in a trailer for the winter because of a house fire. I'm using a 100'-3/4" rubber/hybrid garden hose to drain my "problems" away. I used the rubber/hybrid garden hose. The cable is not recommended for standard garden hose construction. The hybrid is a thicker construction. So far no problems using the hybrid hose. I don't know if it's a recommended hose or not. I wrapped the heat cable around the hose an encased it in foam pipe insulation. I bought two of these cables and duplicated the wrapping and insulation on another 100'-3/4" hose, I'm in two trailers. So far we have had several nights in a row with temps at or under 11 degrees. No problems with freezing. Besides price/length the second reason I choose this heat cable is it is self regulated, so it's on only when needed. I would recommend this cable, and you have choose of different lengths.
