A Sliding Shelf (Pull Out Shelf) from SlidingShelf.com in "Full-Depth" means the Sliding Shelf will be a full 3" Tall on all 4 sides.
The advantages of 3" sides on your Pull Out Shelves are:
Tall enough to keep items from falling off the sides.
Short enough to still see everything that is on your Sliding Shelves.
Every Sliding Shelf on this page is Full-Depth. You will find Birch, Maple, Oak, and even Paintable Sliding Shelves. We also manufacture a Poplar wood Sliding Shelf for ShelfThatGlides.com . (One of our Sister Sites).
