Greenhouse Side Wall Crank Roll-up for Ventilation
Makes greenhouse ventilation a breeze! (Get it?)
Simply raise and lower the entire sidewall of your greenhouse with a manual crank from Light Dep Solutions. Similar to a socket wrench, it will lock in place and not let gravity wind itself back. This is a must for all greenhouse growers.
Connects to 1 3/8″ rolling bar. Don’t forget 1″ tarp clips!
10′ sections of 2.5″ aluminum rolling bar with the recessed channel built in. Included connectors splice the sections together to create a rigid, superior rolling bar. Comes with motor shaft adapters, and bar connectors. These can be expensive to ship.
