What I did was to measure the space between the top-most reel and the snug cover and then sawed off the top of an empty, plastic film container to use as the "spacer" to snug down the ss reels. With this spacer, I do not hear my ss reels slide around for the end-over-end agitation. If you need additional details, email me off-line.(posted 8198 days ago)Hope this helps...
