Cavity Sliders CaviTrack Pocket Door Track System

We've been restoring an antique house with lots of "hidden staircases/stairwells" and other unique architectural features. I needed a sliding "barn" door to close off one of those hidden staircases between the kitchen below and a guest suite above. Regular barn door hardware was not going to work because even if you use the ceiling mounted barn door hardware there would be a gap at the top when the door was closed across the stairwell. That would let light and sound up through the stairwell which is what we were trying to eliminate. Enter the Cavity Sliders. Their website was very good and I called their technical department to ask further questions, prior to searching for an appropriate door. The man I spoke to was fabulous and went through dimensions and function with me. Because of that conversation, I understood what size door I needed to look for and which cavity slider I should use. The hardware allows for a pocket door application without a pocket. Because it is recessed into the ceiling, there is little (1/8") gap at the top. We installed a half round molding on the inside side, in the opening and that takes care of the 1/8". We used the slider without "wings" (that is better if you are a new build because it tucks the drywall in on either side.) We used the one without "wings" that was fastened to the joists and furring because we had already put a new ceiling in the kitchen several months prior. The rails, which are flush to the ceiling, were painted out with the ceiling paint, making them virtually unnoticeable. We mounted a heavy period door (84" x 32") and used the carriage that handled up to 200 lbs. Works smoothly. The directions were very well written with good tips for installation. I can't be happier with the results. It does everything I needed it to do and looks fantastic. One Note: I want to give this 5 stars, but there is no designation on the stars in this review to allow me to know if I'm picking a 1 or a 5 - so if the number doesn't seem right, just know this - it is a 5 star product all day.
