I found the same issue with WST. Used WST when couldn't find Greendot. Then I changed to e3 (really liked & only 16gr needed) then to 700X.👍 thanks for the reply. I feel like a moron but at least it’s an easy fix.
Um, no. The dimples are not there to grip the grommet. It's dimples up so it doesn't slide between the frame and the charge bar.The brass washer sits between the bottles neoprene/rubber grommet and the bar, with the brass washer positioned with bumps "up", whereby to grip the grommet and stay in place thereby.
