I'm writing from Bermuda to enquire if you can assist me in identifying and in supplying me with a set of rollers for two different NuPrime sliding glass windows (that have seen much better days!). I would need 4 rollers for each window and I'm sending a photo of the bottom of each of the two windows.

My intention is to replace the windows but I have to make do with them if possible for a few months before making renovations.

Your assistance would be most appreciated
