Bayliss Mk7 Triple Spring Autovent, Gabriel Ash AC1552
This record covers the Bayliss Mk7 Triple Spring autovent supplied by Gabriel Ash under product number AC1552, rather than an unspecified standard Mk7. The official greenhouse-maker listing describes an approximately 12-inch unit, a maximum opening of about 12 inches and a vent-lifting specification of up to 6 kilograms. It also supplies stainless-steel fixings and a cedar mounting block for a Gabriel Ash greenhouse. Those mounting details are central to the purchase: an opener's lift figure alone does not prove it fits a different frame, hinge arrangement or available travel. Gabriel Ash notes that shelving and staging can interfere with placement, particularly for side windows. Use this as a model-specific option to discuss with the greenhouse supplier, not a universal retrofit recommendation. An automatic opener still needs inspection, unobstructed movement and an overall ventilation plan; maximum opening does not establish adequate cooling for every greenhouse.

Tradeoffs & verification notes

Shelving, staging and vent travel can obstruct operation; this is not a complete ventilation system.
