Quantity: One piece. Material: Galvanized aluminum sheet. Size: Approximately 33.5 cm long, approximately 1 cm error. Weight: 145g. Packaging: OPP bag. HIGH SENSITIVITY: This replacement cylinder contains wax that automatically reacts to temperature changes. Versatile: Compatible with most single or double spring-loaded greenhouse openers, suitable for cold frames, greenhouses, and automobiles. Rustproof Material: The replacement cylinder is made of all-aluminum stainless steel to prevent oxidation and extend its lifespan. How it Works: Operates by temperature. When the temperature rises, the gas heats up, increasing the gas pressure. The spring force pushes the gas outward (opening the window). When the temperature drops (cooling the cylinder), the spring pushes it back (closing the window). High-quality product.
