I purchased these to protect a 50 Amp cord and water hose for an RV. They are heavy duty and actually better then I thought they would be. The heated water hose is a tight fit, but it does fit. The regular water hose will definitely fit. The 50 Amp cord sits in the channels perfectly. The cover (yellow) does blow up if it’s windy out, but I consider that an added bonus to deter the unsupervised boy in the RV park that keeps riding his bike over the cord and hose.
