Not Preferred Wheels
Any wheel from a local pet store.
Some wheels that you get from the pet store are open on both sides with stands that connect to both sides. These are extremely dangerous because, gliders like to jump in and out while it it spinning and this could cause them to get wedged into where these axles connect. We would prefer that you go with one of the ones listed above. We have even listed the links for them.
