Category ：1. Bottom drawer slide. 2. Steel ball drawer slide. 3. Roller drawer slide.

choose：1. Specific gravity: usually refers to the weight of the same length or volume unit, here it refers to the weight of drawer slides of the same type (such as two rails). 2. Surface treatment: This can be seen with the naked eye as good or bad. You don't need to listen to too many sales statements, you will understand naturally after reading them. 3. Structure and Material: Based on the thickness of the metal material cross-section of the drawer slide and its structure, the quality of the drawer slide that usually uses many plastic components is not as good as that of the all metal slide. 4. Applicability: You can feel the weight and force of the drawer slide by stretching it.

The three slide rails are composed of inner rails (movable rails), middle rails, and outer rails (fixed rails). The pull-out length of the two slide rails is generally about 3/4 of that of the drawer (except for the double-layer two ball slide rails), while the three slide rails can pull out the entire drawer because the three slide rails can fully pull out the drawer, making it more convenient to use than the two slide rails. The ball bearings are evenly stressed, smoothly pushed and pulled, and provide silent cushioning.
