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. This RT Cold Frame Package is equipped with our Economy Roll-Up curtains for ventilation and with roll-up curtain doors on the ends. Its 2-piece bow assemblies make for simple installation.
