💡 How do heavy duty nylon wheels improve slide performance compared to standard plastic rollers?

- Sturdy nylon composition handles daily opening and closing cycles
- Electroplated metal stems block moisture buildup along rail edges
- Quick install design requires basic hand tools already in your drawer
