Hand cranks are used for manually pulling greenhouse sidewall curtains. If you have a smaller greenhouse that does not use automation, you can use hand cranks to pull your curtains and save on electricity costs. You will need a side wall guide pipe (HTD-SWRGP) for the reeler to roll up and down during operation.
