This 35mm nylon lined passing ring is designed to work with either the 7cm passing or ceiling brackets. The innovative c-shape design allows the ring to move along the pole, passing the bracket freely, perfect for single draw curtains or longer length windows. The passing ring has a flat front giving it a contemporary look that is available in 4 metallic finishes Nylon pips sit inside the top of the ring, allowing the rings to glide along your pole with ease and eliminating the ringing sound of metal on metal. We recommend using a draw rod with passing brackets, which guides the rings across the pole and passing bracket without any downward force for a smoother operation. Draw rods also protect your curtain fabric by avoiding the need to touch your curtains, keeping them looking new for longer. Note: Passing rings will only work with passing brackets and are not suitable eyelets or normal curtain rings.
