When putting new shelf’s in, you’ll need to take measurements of how long the width is of your cabinet or pantry. I bought the longest pieces of shelving & then used my husbands cutter to cut them the length I needed them to fit into our pantry. I took measurements of how tall the pantry was & got 2 of the straight pieces to put on the back wall (don’t do 1, you need 2 for support) Having these, you are able to move the shelving around wherever you want them!! 10 years from now you can move them to be positioned different if you want them!! That’s why I love these so much!! Then you’ll also need 2 rack supporters for under each shelf. We also got a set of baskets. We put 2 in the pantry & used 2 in our laundry closet also!! http://liketk.it/2F0Vp liketkit @liketoknow.it LTKunder100 LTKhome pantry closet organization shelfs shelving baskets wireshelfs homedepot homeremodeling homereno
