The Redpath self-locking manual Eziwinder roll up wall winch is simple to install, easy to operate and a cost-effective sidewall ventilation system. A roll up wall system will supply substantial control over the internal environment and may be adapted to most building designs. The Eziwinder winch incorporates a unique self-locking all metal gearbox that will lock the roll up wall in the position that the operator requires. Simply turn the handle and the 5.5:1 reduction ratio allows easy winding of the up to 50m length roll up wall.
A steel round guide tube (25.4mm O/D outer diameter) is located vertically through the roller guide of the winch itself and may be purchased as a separate part if you do not have this.
The roll up wall tube that runs the length of the wall horizontally and is turned by the Eziwinder winch to winder the wall up is a 33mm O/D steel tube section; lengths are as shown below, – order as many as required for your length wall.  The tube is “swagged” at one end so that it may sleeve together, small ‘wafer head” screws (four per join) will be needed to lock the joints together.
The other part of the roll up wall system is the “Polyclamp” grips – that secure the roll up wall material to the rolling pipe. (Allow a minimum of one Polyclamp per metre)
Redpath recommend Polyweave reinforced greenhouse film for the roll up wall sheeting (see below) + windbreak wall screening (see below) for the outer barrier netting may be used to hold the roll up wall against the greenhouse poles. If windbreak is not used, then some Polybelt webbed strapping will be needed to keep the roll up wall tight against the poles of the building.
