i bought 24'' rails so dont have a use for these rails. if you need to make these shorter it is possible to cut them and make them work for your setup with the right tools. come with legs to prop on the edge of the aquarium. you can also buy the hanging kit and hang them. heres the link to the rails. They cost 59.95 plus shipping new. these are basically new. no flaws.
