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.

Great for everyday use
We use these daily. I buy the complete set then boxes of each to refill. Very sturdy utensils. Size is perfect. Very easy to clean to use after dinner for deserts. Knives work very well and fork ends are sharp enough to stick in your food to eat. Only brand we use now.

Great quality!
These are every bit as good as the more expensive plastic ware. They’re thick and sturdy. I particularly like the cutouts in the handle. They’re easier for me to grip and keep ahold of. Extremely happy with this purchase.

perfect for daily use — not too thin, not overly thick
Style: 200 Count, Style: 200 Count
I bought the Vanity Fair Everyday Paper Napkins for everyday family meals, and they’ve been great. They’re soft and smooth, but still durable enough to handle spills without falling apart. The size is perfect for daily use — not too thin, not overly thick — just right for kids and adults. I also like that they feel a bit more premium than basic napkins, which makes the table look nicer even for simple dinners. The 200-count pack lasts a while, so it’s a good value for the price. Simple, reliable, and perfect for everyday use.

Perfect balance of softness and durability for everyday use.
Style: 400 Count
Great everyday napkins – good value for the price I’ve been buying Vanity Fair Everyday napkins for a while now, and they’re perfect for daily use. They’re soft enough to feel comfortable but still strong and absorbent. They don’t fall apart easily, even with messy meals or spills. The value pack is especially convenient and lasts a long time, which makes it a great option for families or regular use. They’re not overly thick like premium dinner napkins, but for everyday meals, lunches, or kids’ snacks, they work perfectly. Overall, a reliable, affordable choice that I keep reordering.

Multi use…
Style: 200 Count, Style: 200 Count
I love these Vanity Fair Napkins. They fit perfectly in my counter dispenser. They are a nice, attractive napkin whether for breakfast, lunch or dinner. And they are at a good price point. But truth be told, they come in handy when you have a cold. Grab a handful and take along with you for blowing your nose. They are stronger than bath tissue, yet softer than a paper towel and strong enough for all your congestion.
