The D-Line 13-Piece Cable Raceway Accessory Multipack includes 13 clip-over accessories with rear grip tabs and a robust ABS material. These accessories are designed to be easily installed and can be painted if needed. Additionally, they are able to fit in the gap between a flat surface and the D-Line length thanks to the depth of the rear foam-tape, making them forgiving of poor cuts and imprecise measuring. For best results, use a fine sandpaper to scuff the surface before painting.
