The Ultimate Bundle is the whole package. This value kit comes with 2 boxes of the PROCORE panel, 20 of our most popular hooks, and shelves and baskets. Everything you need to get your space organized. The newest member of the Proslat family promises over 2X the strength of regular slatwall. The key to this panel is its aluminum core. This patent pending design uses PVC only as an aesthetic finish and relies on the aluminum to do the heavy lifting. It is not a replacement for the original Proslat PVC panel, but rather an enhancement to the category. The PROCORE panel will satisfy the needs of customers with 24 inch stud centers while maximizing load strength. Proslat's original panel designed for 16 inch studs is still a great option for many homeowners, its strength is still your best bet economically (holds up to 75 lbs. per linear foot), however more new builds today are designed with 24 inch studs. NOTE: PROCORE PVC Slatwall and PROCORE trims cannot be installed in conjunction with the original PVC Slatwall.
