Chris, The track I used is by EPCO and distributed by wholesale hardware suppliers. An online company called CRL also sells a similar style. I use a double track on the four sides of the opening, and then a single shoe track that the roller guides run on in the bottom double track. The .25" glass sits in a vinyl molding and then is pressure fit inside the channel of the H track that conceals the rollers. I used the plastic rollers because they produce less sound than the metal ones when rolled. Hope that helps.
