Joalock Clamp is an innovative product that allows to easily change the existing single-plastic film-covered greenhouse into dual- or multiple-plastic film-covered greenhouse by simply locking it to the framework of the existing greenhouse. 

Dual- or multiple-plastic film-covered greenhouse enables farmers to grow crops at lower energy costs even in the winter season because of its high thermal efficiency. 

However because of the high cost involved in its construction, most farmers could not easily decide to build the dual- or multiple-plastic film-covered greenhouse. 

Now JOALOCK Clamp lowers such financial burdens so that farmers can cultivate lucrative crops in the winter to increase their earnings. Not only raising the competitiveness of farmers but also according with eco-friendly policies, JOALOCK Clamp is really the essential greenhouse equipment.
