{"product_id":"romados-auto-vent-opener-2-pack","title":"Automatic Vent Opener - 2 Pack","description":"\u003cp\u003eA vent opener that runs on nothing at all. A wax-filled cylinder expands as the air warms and pushes the vent open, then contracts and closes it as the temperature falls - no power, no batteries, no wiring. It starts opening between 15C and 25C, which is roughly the point at which a closed cold frame begins to cook its contents on a bright day.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo openers per pack\u003c\/li\u003e\n  \u003cli\u003eBegins opening at 15-25C (60-77F)\u003c\/li\u003e\n  \u003cli\u003eLift capacity 6.8kg (15 lb)\u003c\/li\u003e\n  \u003cli\u003eMaximum opening distance 45.7cm (18in)\u003c\/li\u003e\n  \u003cli\u003ePowder-coated aluminium alloy frame\u003c\/li\u003e\n  \u003cli\u003eDual stainless steel springs\u003c\/li\u003e\n  \u003cli\u003eTemperature-sensitive hydraulic wax-type cylinder actuator\u003c\/li\u003e\n  \u003cli\u003eAdjustable opening angle\u003c\/li\u003e\n  \u003cli\u003eRequires no electricity and no batteries\u003c\/li\u003e\n  \u003cli\u003e1-year manufacturer warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFits most greenhouse roof windows, roof vents and garden cold frames; a PDF fitting manual is provided.
