I would not recommend hanging with drywall anchors as double and triple stack units get quite heavy. These racks are very strong and if you have a nail finder and spirit level they are not that difficult to install. The hooks are modular so you can easily adjust the distance between them, but with two separate mounting brackets, hanging space is still somewhat limited. But I was able to hang up 4 shovels, three rakes, a pitchfork, a hoe, pruning shears and an (electric) sweeper, a blower and a cordless saw without any problems. Noticeable space savings compared to the replaced individual brackets.
