Run out of headroom in a Bonanza 0.35? This extension panel set lifts the cabinet by 56cm, so the finished height comes to 232cm. That gap matters when a plant stretches up or when a light needs hanging further off the canopy to spread its coverage.
You get a replacement back panel with the air inlet holes already cut. The outlet and cable holes sit in the extension section, so once it is bolted on the airflow path stays exactly as the cabinet was designed. A lock is supplied to match the original doors.
