Gradus CL05/LB10 is a two-piece PVC-u flooring profile designed to house the Gradus LED floor loom or Interlok Advance LED lighting system for walkway and aisle illumination. It has a 9mm gauge in order to accommodate medium to heavy gauge carpets. The base is fitted to the floor first to house the LED floor loom or Interlok Advance LED strip, then the top is clipped into place. The top is supplied as clear or smoked so that light can shine through. When fitted, the compressed thickness of the carpet should always be a tight fit to the internal gauge of the combined top/base profile.
