The PRIME LINE PRODUCTS PL 14268 is a metal miter-cut screen frame corner designed for aluminum lip-framed window and door screens. Each corner is fabricated from aluminum at a .040 gauge and cut at a precise 45-degree miter angle for a tight, concealed fit inside the frame channel. The part is sized for 3/4 inch by 7/16 inch screen frame stock with a 1/2 inch lip. This pack contains 100 individual corners, making it well suited for shop restocking or multi-unit screen replacement jobs. Installation is straightforward and typically handled by glaziers, screen repair technicians, or general contractors.
These frame corners are used in the fabrication and repair of aluminum lip-framed window and door screens in residential and light commercial applications. The concealed design fits flush inside the frame channel, keeping the finished screen face clean and hardware-free. The 45-degree mitered profile distributes stress across the corner joint, supporting long-term structural integrity of the screen assembly. With 100 pieces per pack and a package quantity of 6 packs per case, this SKU is practical for screen shops or maintenance departments managing high-volume repair work.
Designed for use with aluminum lip-framed screens built on 3/4 inch by 7/16 inch frame stock with a 1/2 inch lip channel. Fits standard concealed-corner aluminum screen frame systems.
Power tools are generally not required for corner insertion; a rubber mallet or corner tool is typically used to seat the corner fully into the frame channel. Confirm frame dimensions before installation to ensure the 3/4 inch by 7/16 inch profile matches existing stock. Handle cut aluminum corners with care to avoid edge burrs during assembly.
