I purchased this to have a place to put my trimmers inside my enclosed landscape trailer. It has room for 3 trimmers, and removes them from the wall enough so they are not touching the wall.  What holds the trimmers in places is a 1/4" spring loaded lever that presses against the trimmers shaft.  The spring on the trimmer rack and the lever lock thing is heavy duty enough that it will last.  I was about to post this review and give it 5 out of 5 but I noticed after a few days of using it and driving around a little bit I could see that there was wear marks where the trimmers shaft was being held into place, I put about 3 rounds of electrical tape on the shaft in a 2 inch swath and it seemed to resolve the issue.
