I have four steel shelves measuring 24x48 inches. They are in great condition. The shelf with the cross braces has hardware the shelves sit in and holes you can use to bolt the shelves to the uprights. As shown on photos 1-3. The other three have bolts holding angle brackets to the shelves and to the uprights. Photos 4 & 5. I have extra hardware we can install if anything isn’t secure enough for you. If you want to haggle over price or trade for reloading stuff call me.
