One thing to note... My doors are stacked... some of them are 5 doors wide and I must have 15+ doors that slide all over the house. The tracks are quite large, and fill up with water in the winter durring a storm. I think this contributes to the wear on the roller bearings significantly.
I've attached some pictures of my roller. The dimensions are very slightly different than the 81-261 model... but it doesn't seem like so much that it would make a difference.
Thanks in advance... really want some sliding doors that don't have to be lifted every time I want to open them!!!
