Tools & Supplies Greenhouse and Tunnel Supplies Vents and Vent Openers

High Tunnel Vent w/ Auto Opener – 18" x 18"

Product ID: 7353

Installs quickly into the plastic, no framing required

Louvered aluminum vent with a temperature-adjustable wax cylinder actuator that automatically opens in summer, providing additional ventilation through the tunnel's end wall. Provides a level of insurance for manually vented tunnels with roll-up sides to help prevent a temperature spike when the tunnel is vented a bit later than desired. Also can be used manually (cylinder detached) for winter growing, since ventilation is still very important for disease prevention. Each vent includes Poly Latch Wire and Channel for fast installation.
