Drawer Slides / Guides

Another important component in selecting case goods is what type of drawer slides or guides are used. While there are numerous variations and makers, it basically boils down to these two:

• Wood-on-wood rails are the most basic type of drawer slide, consisting of either a single, center-mounted rail or two rails spaced toward the edges of the drawer. As the name implies, this slide works by wood-on-wood contact. These types of slides aren't the smoothest and usually don't age well. Unless you're buying an older or antique piece, avoid chests and drawers that use this method.
• There are many variations of this next type of drawer slide, but it normally consists of side or under-mounted rails that employ a smooth ball-bearing or wheel action. This type of slide uses a 4-piece system, whereby a track is affixed to each side of the drawer opening and the corresponding guide attached to the outside of the drawer. This type of guide can be made of metal or plastic, or sometimes a combination of each. Many of these drawer slides are equipped with a stopping mechanism to prevent the drawer from coming completely out.
