Drawer slides often have dimensions and purchasing methods

The common sizes of drawer slides are: 10 inches, 12 inches, 14 inches, 16 inches, 18 inches, 20 inches. More sizes can be customized.

First, categories
1. Bottom drawer slide.
2. Steel ball drawer slide.
3. Roller drawer slide.

Second, purchase
1. Specific gravity: usually refers to the weight of the same length or volume unit, here refers to the weight of the drawer slide of the same type (such as two rails).
2. Surface treatment: This point can be seen with the naked eye. You don't need to listen to too many sales words, you will understand it when you see it.
3. Structure and material: Look at the thickness of the cross-sectional surface of the metal material of the drawer slide, as well as its structure, usually the quality of the drawer slide rail using a lot of plastic parts is not as good as the all-metal slide.
4. Applicability: Stretch the drawer slide rail to feel the weight, strength and so on.

Third, the commonly used drawer slide rail is three sections
The three-section slide rail is composed of the inner rail (movable rail), the middle rail, and the outer rail (fixed rail). The length of the two-section slide rail can generally be about 3/4 of the drawer (except for the double-layer two-section ball slide), while the three-section slide rail can pull out the entire drawer, because the three-section slide rail can be pulled out of the drawer, which is more convenient in use than the two-section slide. The ball is evenly stressed, the push and pull are smooth, and the cushioning is silent.
