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!
