I didn't know how much I needed until I installed it in the laundry room. It comes with screws, glue and strong double-sided tape. I taped it in place in no time and it's holding up really well. My only gripe is that I wish it had 8 pieces of double sided tape instead of 6. This is a great purchase and keeps my mops, brooms, dust pans and reusable plastic gloves well organized.
