If you are familiar with using sliding rack shelves, you probably know that most do not positively lock in the closed position. This can be an annoyance when utilizing the rack. This can be a problem whilst touring and gigging. The sliding rack shelf can slide in and out during transit (especially in a fly style rack) and cause wear/damage to the shelf, your gear, or even the cabling within the rack. During a gig the shelf can slide out making it easy for a crew member, yourself, or your drummer’s sisters girlfriends husband that “used to play guitar in high school” to accidentally catch the shelf and knock the rack down.
