This Bayliss MK7 is an extremely reliable, British made, automatic vent opener suitable for use on nearly all greenhouses.

It is operated by a stainless steel cylinder containing a mineral wax which expands with heat; this pushes a piston causing the vent to open. As the temperature falls the wax contracts and a strong stainless steel spring closes the opener.

Product Description

Suitable for roof vents weighing up to 14lbs, approx. 76cm x 76cm.

Bolts on to aluminium greenhouses (fixings supplied) - for wooden greenhouses it is attached by wood screws (not supplied).

Fitting neatly close to the glass the opener does not protrude into the greenhouse (so you don't bang your head!), as the window opens the auto opener is pulled into the window hole.

Satin anodised aluminium unit approx. 29cm long which will lift a roof vent weighing up to 6kg.

Can be set to start opening the vent at any temperature between 12-25º Centigrade/55-75º Fahrenheit, and gives a maximum window opening of 30cm.
