Finding your book drop constantly overflowing? Try our 70 S-Series Supermax Versa dual drop. The 70 size is like having two 50 units in one. The unibody design allows for bigger graphic decals and it is a cost efficient way to get multiple units. Each side can hold up to 380 standard size (6x9") books or 950 media cases for a combined total of 760 standard size (6x9") books or 1900 media cases. We even include deals so you can label one side for books and one for media if you want a dedicated drop for each. Or you can use both sides for books if you have a larger or higher volume library.
