Prime Line Products B 639 Screen Door Tension Spring Roller

Product Description

The PRIME LINE PRODUCTS B 639 is a two-piece kit containing a 1-inch screen door tension spring and roller, sold together as a matched set. This hardware is designed to maintain proper tension on screen door frames, keeping the door aligned and operating smoothly within its track. The assembly is a direct replacement component for screen doors that have lost spring tension or have worn rollers, and is typically installed by a window and door technician or an experienced general contractor.

Basic hand tools are sufficient for most screen door roller installations. Follow the door manufacturer's guidance for proper spring tension adjustment after fitting.
