FLOOR BOX RKN4KO

Floor boxes without collars for recessed installation Recessed installation is suitable when the surface concrete on top of the hollow slab is very thin or non-existent. In recessed installation, the hollow slab itself serves as the conduit, and no separate box is needed for the device outlets. If a sufficiently thick surface concrete is applied on top of the hollow slab, the floor channel or installation pipes can also be used as the conduit. In recessed installation, the hollow slab diameter must always be considered along with how the hollow slab is opened. Recessed installation also makes it easier to achieve the required depth for device outlets. The cable exit opening can be locked either open or closed. RKSN floor boxes feature a cable guide that prevents cables from getting caught between the lid and the box. Additional information on page 9 of the PDF brochure. RKSN2 4 KR V20 2x3 modules Min.
