UYGALAXY 2PCS Greenhouse Sidewall Roll-Up Winch – Easy Ventilation

Enhance greenhouse airflow with a reliable sidewall roll-up winch

The UYGALAXY 2PCS Greenhouse Sidewall Manual Film Roll Up Winch delivers controlled, smooth operation for adjusting greenhouse sidewalls. Designed to help you manage ventilation with less effort, this two-piece kit supports better air movement and more predictable interior conditions without relying on constant manual lifting.

Included as a pair, these winches are ready to install on opposite sides, offering symmetric opening capabilities and balanced airflow. Built with practical sizing in mind, they pair with standard piping systems to fit many existing greenhouses, from compact setups to mid-sized structures.

Key benefits at a glance

• Self Locking; Automatic brake holds sidewall in place
• Max roll length: 393ft (120m); Max roll height: 4.9ft (1.5m)
• 4:1 gear ratio for easy cranking
• Mechanical brake holds sidewall in place
• Recommend 3/4" ID pipe (or 1" OD tube) for climbing pole and roll bar

How it helps in real use

On warm days, you can roll up sidewalls to introduce cooling air, while keeping the openings controlled and secure. When humidity or temperature shifts, the dual-winch setup allows you to adjust both sides in a coordinated fashion, creating a balanced opening profile without wrestling with heavy fabric alone.

The combination of a robust max roll length and a practical roll height gives you flexibility across different greenhouse shapes. The 4:1 gear ratio reduces the effort required to operate the crank, while the dual braking systems provide confident stops and steady positioning—great for daily adjustments and when wind conditions change.

Fit, installation, and use tips

• Pair with standard 3/4" ID pipes or 1" OD tubes for climbing poles and roll bars
• Position winches to achieve balanced openings on both sides for even airflow
• Regularly check brackets and cables for wear and tightness to maintain performance

Durable design and practical considerations

Engineered for greenhouse environments, the kit emphasizes reliable grip, straightforward maintenance, and durable hardware that resists typical outdoor moisture and pollen exposure. The compact roll height helps when ceiling clearance is a consideration, while the long roll length supports longer runs along the wall.
