There are a host of shelf edge Mount solutions, some temporary, other quick-mount/quick change for rapid merchandising, some permanent mount. I am forced to classify this C-Channel Mount in that later category, and call it “Super-Duty” because far lighter gauge / lighter screwed designs exist, as well as narrower heavy gauge versions. If my goal were permanence for aisle signs as big as this, I would certainly consider this mount. But by all means, please do research componentry further. You might find a system that even better suites your store needs. PS: Thumb screw tightening might eliminate the need for your staff to always carry a screwdriver wherever they go.
