An extremely reliable automatic vent opener the Bayliss XL is activated 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 12lbs, approx. 76cm x 61cm.

It can be clamped onto aluminium greenhouses - no need for any drilling. If a more permanent fixing is required it can also be bolted on - 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!).

Satin anodised unit approx. 28cm long which exerts a load of 5Kg i.e. it will lift a vent weighing up to 10Kg.

Can be set to start opening the vent at any temperature between 12-18º Centigrade/55-65º Fahrenheit, giving a maximum window opening of 30cm.
