Ryobi fan holders are available for any type of crate, and version of fan. We can make these hooks with either clips on each end or O rings, depedning on the type of crate you have. Before you purchase these fan holders please know which style fan you have; the older model has a hook at the bottom, and the newer model does not (as seen on the fan in the photos). Rufflands will need the O ring version to loop on the door hooks. Any wire crate will need the clip end version to be able to hook on the bars of the crate door.
 
If you have any questions about what style you may need to order, don't hesitate to reach out with any questions!
