These straps are here to keep your dog cool in their kennel. These are designed for plastic (Ruffland- style) kennels and the “older” Ryobi fans. Check your equipment to see if it is compatible and let us know if you have questions. Each set is 2 straps, enough for one fan. Each strap has a clip on one end (fan side) and a 1inch D ring on the other (kennel side).
