XL Soft Fruit Solutions products

XL`s side vent system uses a gearbox assembly which is operated by an endless chain. It is very easy to operate and takes much less effort than the tradtional cranked handle. Can be retrofitted to any straight sided tunnel or greenhouse. A clutch inside the gearbox holds the central torsion bar steady at any postion you choose between fully open and fully closed. It runs up a guide rail (see photo) which holds it in place.
