Description

The PRIME LINE PRODUCTS PL 14294 is a 100-pack of metal miter screen frame corners designed for securing and squaring screen frame assemblies at 45-degree miter joints. Each corner insert fits inside the hollow channel of compatible aluminum or steel screen frame extrusions, holding mitered ends together without fasteners. At 0.75 inches by 0.3125 inches, these corners are sized to fit specific screen frame profiles. Installers in window and door service, glazing, and general building maintenance use these for screen fabrication and repair work in both residential and light commercial settings.

These miter corners are intended for use with screen frame extrusion systems where a tight, clean corner joint is required. The metal construction provides durability over plastic alternatives, resisting flex and deformation under tension from the screen mesh. Compatible frames include those used in standard window and sliding door screen applications. The pack quantity of 100 pieces supports production-volume screen shops or contractors handling multiple screen replacement jobs at once.

Installation Notes

Installation is typically performed by window and door technicians or general contractors during screen fabrication or field repair. Cut frame extrusions to length at a 45-degree miter before inserting the corner pieces into the open channel ends. No special tools are required beyond a miter saw or frame cutter and a rubber mallet for seating the corners fully. Ensure frame ends are cut cleanly and squarely to achieve a flush, gap-free joint before stretching and spline-securing the screen mesh.
