Review on IRONCK Industrial Bookshelf Double Wide 6-Tier, Open Large Bookcase, Wood And Metal Bookshelves For Home Office, Easy Assembly by James Bull

These bookshelves look just as great in person as they did in the product listing! The bookshelf assembly instructions are easy to understand and assembly took roughly 20mins. One thing not included in the instructions was the size of the drill bit needed to pre-drill the wall mounting brackets to prevent your bookshelf from toppling over. I found that a 1/4 inch drill bit provides enough clearance for you to hammer in the plastic wall anchors into the holes and for the screws to remain secure after mounting.
