This is a pack of two Bayliss Mk.7 autovents. These autovents automatically opens and closes hinged vents. The autovent uses energy from the sun and surrounding air, the hotter the temperature the wider the vent will open. The Bayliss MK7 Autovent is supplied in a satin anodised finish, with all the fixings and instructions. Designed for timber or aluminium framed vents measuring up to 60cm x 60cm (2ft x 2ft), has a lift load of up to 6kg and opens to a maximum of 30cm (8"). Can be set to start opening from 12°C (55F) The autovents strong metal tube contains a mineral wax which expands with heat. This pushes a piston which opens the vent via a balanced linkage. As the temperature drops, the wax shrinks and a strong stainless steel spring closes the vent and resets the piston. All Bayliss products are guaranteed for two years against faulty manufacture. They are designed and tested to last for many years and are fully serviceable.

Awesome vent opener
I am very happy with this vent opener. It works perfectly. Nice compact design. Super fast shipping from the UK. It is a quality product and I would gladly give it more than 5 stars if possible. If you need a greenhouse vent opener, buy this one. You will not be disappointed!

Only 1 Vent delivered - TWICE
This product seemed perfect for our greenhouse needs. I ordered two, expecting to receive 4 vents. I only received two. I kept the two and "returned" one order. I then re-ordered and AGAIN only received half the order, one vent. I contacted Amazon but since this is an outside seller it is a much more complicated process. They recommended returning the item and ordering again but this will only continue the vicious cycle. I will be ordering from another seller moving forward. I would warn anyone looking at this item that there is a chance they may not receive the full order of 2 vents and to beware.

Reliable, solid and worth the difference in price compared with cheaper alternative (Ya-tube)
Bought as p/o a santa barbera greenhouse kit. Work reliably. Can now compare to Ya-tube openers you can also find on amazon. Like night and day better quality. Everything about the Ya-tubes is cheaper, flimsier and smaller (can’t lift as much) . Don’t hesitate to spend the extra money for these.
