Gradus DLA45 is an aluminium profile designed to house the Gradus Continuity and Interlok Advance LED lighting systems for walkway and aisle illumination. It can be used as a floor profile to be installed with heavy gauge carpet, or can be used as a feature strip on walls. DLA45 incorporates the LR1238 PVC-u tube that in turn houses the Continuity and Interlok Advance LED lighting systems. The clear tube allows the lighting to shine out of the profile. If installed with carpet, the compressed thickness of the carpet should always be a tight fit to the gauge of the profile.
