Prime Line Products B 570 Screen Door Tension Spring 2 Pack

Product Description

The PRIME LINE PRODUCTS B 570 is a 1-inch plastic tension spring with roller designed for screen door applications. This two-pack provides the hardware needed to maintain proper screen door alignment and closure tension. The spring and roller assembly keeps screen doors tracking smoothly in their frames, reducing sag and preventing the door from dragging or misaligning during operation. It is a common service part installed by general contractors, handymen, and facilities maintenance professionals performing screen door repairs on residential and light commercial buildings.

This tension spring is suited for standard screen door frames requiring a 1-inch plastic spring-and-roller assembly. It is commonly used in repair and replacement scenarios where the original spring has lost tension, broken, or gone missing. The carded two-pack format makes it practical for stocking multiple units for recurring maintenance needs or for completing repairs on double-door setups in a single service call.

Installation Notes

Installation is typically performed by general contractors or maintenance technicians using basic hand tools. Remove the screen door from its frame before servicing the spring and roller components to avoid accidental panel damage. Ensure the replacement spring is seated fully in the frame channel and the roller engages the track correctly before reinstalling the door. Verify door alignment and smooth travel through the full range of motion after installation.
