Replacemt cylinder suitable for Thermofor roof vent openers only
Please note this is the cylinder only, no fittings are included.
Overall length: 200mm (8 inches).
Q. Will this opener fit my greenhouse windows. No, what i really mean is are greenhouse windows a standard size?
A. Most greenhouse roof-vents are around 2' x 2'. The Bayliss XL Vent is recommended for any building that in in an exposed area.
Q. Hi im about to purchase g/house. what is the best base/foundation. ie flags or concrete
A. Paving slabs are generally a better option than concrete as the joints between the slabs allow excess water to drain away.
Q. We bought a Hercules greenhouse from you in 2007 including auto vents. A cylinder needs replacing and it looks the same as this but don't know about the length. Is this one approx. 8 inches including end nuts?
A. Yes, the Replacement cylinder for XL Opener is approximately 8 inches long (including end nuts).

One of the 2 original vent cylinders lasted for 3 years, but started leaking over winter. Replacement delivered promptly.

Bought this as a replacement for the 18 year-old ones in my window vents. They were easy to swap.

Replaced similar product and an immediate improvement on opening greenhouse vent. Trusting these will prove to be more reliable than the previous item supplied with the greenhouse about three years ago.
