Prime Line Products Pl 15030 Aluminum Corner Key 20 Pack

Product Description

The PRIME LINE PRODUCTS PL 15030 is an aluminum corner key designed to reinforce and square up window screen frames at the corners. Each key measures 3/16 inches by 3/16 inches and fits into the mitered corner slots of aluminum or steel screen frame extrusions to hold the frame assembly together. This pack contains 20 individual corner keys, making it well suited for multi-unit service calls or shop stock. Licensed window and screen technicians as well as general contractors handling window screen repair or fabrication will find this a standard consumable for frame assembly work.

This corner key is used in residential window screen repair and new screen frame fabrication. It is installed where screen frame rails meet at 90-degree corners, locking the mitered cuts together to form a rigid frame. The 3/16-inch profile matches common aluminum screen frame channel sizes found in standard residential window and door screens. It is a high-volume, low-cost replacement part stocked by screen shops, glaziers, and general maintenance contractors.

Installation Notes

Installation is typically performed by window screen technicians or general maintenance contractors. Before assembly, ensure the mitered frame corners are clean and free of debris so the key seats fully into the channel. Insert each corner key into the frame extrusion channel at the mitered joint and press the frame halves together until the joint is flush and square. No special tools or fasteners are required, but a rubber mallet may be used to fully seat stubborn joints.
