Terma aims to think differently when conceiving its towel rail designs and the Quadrus Bold has been designed to maximise heat output by having two layers of bars, a full rear layer and forward layer with gaps for towels. The flat bars with closely spaced gap differ from the standard ladder rail creating a fuller looking overall design. The front bars protrude forward from the front of the upright bars and the rear bars are suspended between the uprights which results in a large gap within which to feed the towel. The electric towel rail is pre filled with oil and supplied with a factory-installed heating element (with the selected type of cable), meaning it can be installed and connected with minimal comissioning.
