The PRIME LINE PRODUCTS PL 7727 is a nylon screen frame corner designed for square-cut screen frame assembly and repair. Each corner measures 3/4 inches by 5/16 inches and is molded in gray nylon for durability and resistance to moisture and UV exposure. This pack includes four corners, providing enough hardware to complete a single standard screen frame. Window and door screen installers, glaziers, and maintenance technicians use these corners to build or rebuild aluminum screen frames cleanly and without special tooling.
These screen frame corners are intended for use with square-cut aluminum screen framing. They are suited for residential window and door screen applications where a secure, flush corner connection is required. The gray color coordinates with standard aluminum screen frame finishes. The carded retail packaging makes them easy to source individually for service calls or small repair jobs.
Designed for use with the PRIME LINE PRODUCTS PL14077 screen frame. Verify channel dimensions before installation to confirm fitment with other frame profiles.
No power tools are required for installation. Insert each corner into the mitered or square-cut ends of the aluminum frame channel and press firmly until fully seated. Ensure frame channels are cut cleanly and squarely to achieve a tight corner fit. Screen spline and mesh should be applied after the frame corners are fully secured.
