Although they fit me perfectly, I understand why some complain. Both have rubber seals. But the internal thread, which I don't want, only goes halfway through the pipe and the other half is an unthreaded sliding joint. The threaded portion is next to the flat top of the divider. But they sealed my trays and provide a minimum height to clear water and rain, so overall I'm very happy with my purchase.
