The Smart Box Holder works by placing small ring onto outer face of door front and positioning the backing plate to the inside of door held in place with 4 small screws which are supplied. Boxes such as tissues boxes, glove boxes and more are held in place with stretchy cord. Once the box is attached to the door there is enough space left in cabinet to house extra boxes which make a more efficient work place. Another of Smart Sinks de-clutter range and also proud to wear the Australian Made Logo. Give any surgery a more appealing look when things are inside cabinets and off the benches or walls.
