These came with both long and short screws as well as wall anchors to fit any type of installation. I used the short screws on my cabinet doors. It was so easy! I just power drilled them in and done!The racks are both very sturdy and designed to fit well in cabinet space, allowing for large lids and closure. I fit 13" large lid with plenty of room. Lids don't fall out the bottom or roll around when the door is moved. I fit all 9 of my skillet and pot lids on these 2 racks, without being jammed together. Easy to remove and restock. Would purchase again. So much better than stacking them on the shelf!! I love these.
