Pack of 6 lined rings for the John Lewis stainless steel 30mm curtain pole, for a smooth and quiet glide. We recommend one ring for every 10cm of pole. For example, a 120cm pole would need 12 rings. With its art deco leanings, stainless steel guarantees a clean, sleek and stylish look that's in harmony with any decor. It's a great option for rooms prone to moisture such as bathrooms and kitchens because it resists corrosion, rust and water damage.
