Today we’ll be displaying the two types of sliding mirror closet door rollers; convex and concave and the tracks that work with them. In this video, we’ll first show how convex roller assemblies work with the convex 23-242 sliding closet track. Then we’ll demonstrate how a concave roller assembly works with the concave 23-272 and 23-355 mirrored door tracks. Keep in mind that these tracks are available in a variety of lengths and color options and there are many styles of rollers to choose from. To determine the correct replacement track, First, compare the end profile and dimensions of your original track with the options in the online catalog at SWISCO.com. To see the difference between concave and convex rollers and how the rollers and tracks work together, we’ll show a few examples. First we’ll show how a convex wheel rolls on our 23-242 convex track and now we’ll demonstrate how the concave 23-028 and 23-064 rollers work with the 23-272 and the 23-355 concave tracks.
