The Cleaneo-Caps Q are square fastening sleeves made of white plastic. They are the optimal fastening means for Cleaneo acoustic linear panels with square holes. They can be used to screw directly into the holes in the acoustic panels - thus eliminating the time-consuming filling of the screw heads. The corresponding sheet metal screws (black screws for Cleaneo acoustic panels with black fiber fleece, white screws for panels with white fiber fleece) are included in the scope of delivery.
