Wire shelving minimizes dust accumulation and allows a free circulation of air, greater visibility of stored items and greater light penetration.  Wire shelving can change as quickly as your needs. Posts have grooves at 1" intervals.  A tapered split sleeve snaps together around each post.  Tapered openings in the shelf corners slide over that tapered split sleeves providing a positive lock.  Shelf is assembled in minutes without the use of any special tools.  Shelves are accessible from all sides making maximum use of storage space.
