Probably a long shot but I figured it was worth a shot here.
I was installing a bunch of cylindrical CO’s today and a single Rim CO. While installing the Rim CO I noticed there was a set screw in the box but could not for the life of me figure out in the installation instructions or on the device where it would go. My only thought would be for the tailpiece on the cylinder but it came with a small plastic piece that went down to hold it in place and the hole was not threaded.
Is it possible it’s for the Vertical Rod trim variation? Only difference in the installation instructions for a Vertical Rod was that it came with a spacer that went behind the battery case to allow the rod to run behind it.
