The ClosetMaid® Shelving Tools app takes the guesswork out of buying wire shelving. The application quickly calculates how much wire shelving you’ll need to get the job done as well as what hardware pieces are required for a complete install. Simply choose the shelf type and size that will be used and the needed cut lengths for your custom job. The Calculator will summarize the exact number of shelves necessary noting exactly where to cut and how many caps, brackets, and other hardware pieces are needed.
