Hi all - I picked up a new rack this weekend w/ seven 28 qt tubs. Some tubs fit like a glove, sliding in and out w/o resistance, while others are tight and require a good amount of pressure to get them in. Granted, I'm not using all my might to make them fit, but the resistance is enough to make the tub skip/vibrate/chatter - has to be stressing the snakes a bit each time.

Aside from shorter tubs or shaving some off the top of the sticking tubs - any ideas? Was thinking maybe some sort of dry lube?
