🛠️ Buying Guide
Choose based on weight:
- Go with WGR001 for extremely heavy loads (e.g., bulk bins or mechanical parts).
- For moderate-heavy use, CJ020‑3 or CJ015‑DK is ideal.
Consider airflow & dust:
- Use wire shelves (CJ016‑DK, CJ017‑DK, CJ019‑DK) in breakrooms, pantries, or spaces needing visibility.
Think about mobility:
- Choose CJ019‑DK with wheels for dynamic environments like kitchens, repair shops, or mobile inventory needs.
Match size to fit:
- CJ017‑DK is perfect where width is limited.
- Taller shelves (CJ020‑3) maximize vertical storage.
