Winter Cover Clips help to secure you winter cover to your pool over the Winter months. **If your pool is an Oyster Bay ( by Home & Roam) or Seville ( by Artesian) model swimming pool please send us an email (click on customer service and be sure to email "for online purchases") or call referencing your order # after you have placed your order notifying us of this. This way we can send you the correct style cover clip with your order. Failure to do so will result in you receiving a cover clip that will not work with your pool.
