20′ RT Coldframe

Commercial Vegetable | High Tunnel Production

The 20’ RT Cold Frame is a great structure for overwintering crops when additional growing space is needed.

Thanks to its rectangular tubing construction, this structure is ideal for growers in northern climates with high wind and snow loads or for the southern nurseryman looking for a low profile, low cost overwintering structure. The RT Cold Frame can be equipped with our Economy Roll-Up curtains for ventilation and with zippered end panels for ventilation on the ends of your house. Its 2-piece bow assemblies make for simple installation.
