Wholesale plunger springs for window screens are small mechanical devices used in window screens to provide tension and hold the screen securely in place. These springs are made of high-quality aluminum alloy, making them durable and long-lasting. They are typically cylindrical in shape and feature a plunger mechanism that pushes against the frame of the window, applying force to keep the screen in place. The springs can be easily installed and removed, making it convenient for maintenance or replacement.

The springs come in a variety of sizes to accommodate different types of window screens, and are designed to be used in both residential and commercial settings. They are typically sold in bulk quantities, making them a cost-effective solution for window screen manufacturers, contractors, or repair companies.

In addition to providing tension, these springs also help to reduce the risk of damage to the screen or frame by evenly distributing the force applied. They also allow for easy removal and installation of the window screen, making them an ideal solution for those who need to frequently access their windows.
