Ingenious temperature-sensitive device that automatically opens and closes coldframe lids, greenhouse windows and even skylights. Works throughout the day and maintain a constant interior climate, something impossible to achieve by manual adjustments.

  • Requires no batteries or electricity.
  • It can be adjusted to start opening between 60-77°F. Fully open at 86-90°F. Fully closed at 55°F.
  • Strongly recommended for all our glazed season extenders because it dramatically improves plant growth.
  • The hydraulic cylinder comes with a 1 year warranty. The average lifetime of the cylinder is 5-10 years, although some can last up to 20 years.
  • Screw directly into polycarbonate panels, wood, or metal frames. The Standard Vent Opener can open a hinged window or vent weighing as much as 15 lb. For larger panes use the stronger Gigavent with all metal construction, to lift up to 65 lbs.

Note from the manufacturer: Recommended to lubricate the piston rod yearly, this will help extend the lifetime of the hydraulic cylinder. Don't use solid grease, as dust particles "glues" easily onto the piston rod and can damage the rubber. Also do not forget to unlock the vent in the winter if leaving the vent openers installed. Even a weak winter sun can heat the hydraulic cylinder sufficiently to make it start pushing the piston rod outwards.

Replacement cylinders are available.

Favorite treat of all time for our Maltese pup.
Pattern Name: Lollipop, Size: 0.53 Ounce (Pack of 4)
These are my Maltese dog’s favorite treat. I don’t know if it is the whole combination of shape, taster, tendon location, or that they are from a Turkey, but they are an absolute winner when we have them. Since they are quite expensive, we only get them on occasion. If they were less expensive, even by 10%, I would justify regular purchases of them to myself. I highly recommend them for any size, breed, or reason. They are an exceptionally wonderful treat for my pup. I think I have just found the reason for ordering another order of these Turkey Tendon lollipops for my best friend. Especially since he eats them quite quickly, even though he is only four pounds. And they seem to be quite digestible.

Perfect treat for my Dolcé!
Pattern Name: Bone, Size: 0.53 Ounce (Pack of 4)
My 14 pound Maltipoo LOVES these. It keeps her occupied for a good 30 minutes. Be sure to get the bone-shaped ones because little dogs will choke on the lollipop-shaped ones.

Good value
Pattern Name: Ring, Size: 0.42 Ounce (Pack of 10)
This is a new treat for our sweet girl and she loves it! She’s a small dog so I break them in two and it’s just enough.
