This Bayliss MK7 Triple Spring is an extremely reliable automatic vent opener designed to be fitted to top hinged side windows or light roof vents to hold them firmly in place in windy conditions, with its extra springs to exerting more closing force.

For side windows up to approx.36" x 24" (92cm x 61cm).
Bolts on to aluminium greenhouses (fixings supplied) - for wooden greenhouses it is attached by wood screws (not supplied).
Fits neatly close to the glass the opener does not protrude into the greenhouse.
Satin anodised aluminium unit approx. 11½" (29cm) long which exerts a load of 13lbs (6kg) i.e. it will lift a vent weighing up to 26lbs (12kg).
Can be set to start opening the vent at any temperature between 12-25º Centigrade/55-75º Fahrenheit, giving a maximum window opening of 12" (30cm).
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 & a strong stainless steel spring closes the opener.
Supplied complete with comprehensive installation instructions.

Bayliss guarantee their openers for 2 years but if anything should go wrong after that replacement cylinders are readily available & easy to fit.
