I didn’t install it but my husband did. Apparently I bought the one for hanging on the ceiling but he made it work for the wall. It’s great and removes the clutter in our garage with five bikes!
Works correctly if you use as intended or prep the area.
For those who post pictures of the system failing it is due to not mounting it in a masonry wall as described in the instructions. I placed a sheet of plywood on the wall and mounted to that and the rack nicely holds all of our bikes.
Really made a lot of room in my garage. Comes in two pieces so you have some flexibility with where to I stall them. One rack holds all four of my adult sized family bikes.
