Tennsco(r) Add-A-Stack Shelving System; Top and Base ...

Sand. Order one unit for each stack of tiers. Start with a top and base unit, then add as many filing tiers as needed.

Sturdy steel dividers, four per shelf, are welded between frame and shelf for stability. Rolled edges for safety and embossed structural ribs for strength. Shelf dimensions: 10Hx36Wx13-3/16"D.
