Description
Makes greenhouse ventilation a breeze! (Get it?)
Raise and lower the sidewalls of your greenhouse with ease. Crank is similar to a socket wrench in that it locks in place. Connects to a 1 3/8″ rolling bar.
Keeps your clear plastic nice and tidy, without chance of getting accidentally rolled up in the blackout plastic.
We carry two styles of roll up crank units. Heavy duty blue unit comes with 1 3/8" shaft adapter to attach to roll bar. Red unit does not come with shaft adapter.

The blue units are awesome.
