Buying Guide
- Load capacity: Choose based on expected drawer contents. Heavy-duty options commonly range from 100 to 260 pounds per pair.

- Durability features: Ball bearings reduce friction and wear; electroplated coatings help prevent rust in humid or wet environments.
- Concealment: Concealed under-mount rails deliver a cleaner look and can improve space utilization in tight cabinets.
- Sizing accuracy: Measure drawer length and cabinet depth; choose a slide length that fully fits the available space when closed.
