The Thermorail vertical heated towel rails are designed to help dry your towel and create a design statement in your bathroom particularly in bathrooms with limited wall space. The matt black finish of the VS900HB matches perfectly with your matt black tapware. All Thermorail vertical heated towel rails include an optional towel hook which can be fitted on the rail at the time of install. This hook allows for the towel to be more easily hung over the vertical rail. Whilst the vertical rail will assist in drying your towel, it does have less surface contact than a ladder rail and therefore will be less effective in drying and warming your towel than a ladder. The Thermorail single bar heated towel rails are all 12 volt which means they are safe to be installed anywhere in the bathroom, even close to water. All the 12-volt single bar rails are provided with a transformer in the box.
