Product review (3 stars): There was probably a better way to do it
The end caps fit but there were no instructions as to how to install them. It took a while to figure it out, and I actually had to bend the metal sliding part to get it in. There was probably a better way to do it, but without instructions..... That's the only way I could I could see. Once I got it in, it works so I guess that's what matters most!
