Terma aims to think differently when conceiving its towel rail designs and the Quadrus Slim has been designed with a single layer of ultra flat bars, with closely spaced gap differ from the standard ladder rail creating a fuller looking overall design. The bars protrude forward from the front of the upright bars for a projected look. 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.
