On those bars we want to raise and lower often, we have added load binders like this. We switch the rail from Men’s to Women’s on some bars, as well.
The only problem … they are too easy to open. On this style of load binder we are using a zip tie to ensure it does not open accidentally. (We need cut it off each time we change the rail.)
Leave a comment if you have alternatives to suggest.

UPDATE: Coach Steve from the beautiful city of Nelson, B.C. recommends:
We use this one from American Athletics. It has a locking pin that you have to pull back in order to open it.
