Product Description
The PRIME LINE PRODUCTS PL 15052 is a die-cast zinc corner key designed to repair or replace damaged and broken corner keys in storm window frame assemblies. Sold in a 20-pack, each key measures 3/16 x 3/16 inches and features a non-handed design with 1-way spring clips for secure, directionally flexible installation. This part is suited for window service technicians and glaziers working on residential storm window systems that use triple track frame construction. The zinc die-cast construction provides corrosion resistance and dimensional consistency, making it a reliable direct replacement for worn or failed corner key hardware.
The PL 15052 corner key is used in triple track storm window frame assemblies where the structural corners have cracked, broken, or lost their spring retention. The non-handed design means a single part number covers both left and right corner positions, simplifying service inventory. Typical installs involve removing the existing frame glass or sash, extracting the damaged corner key, and pressing the replacement into position using the integrated 1-way spring clips to lock the frame extrusions in place. This part is commonly stocked by window and door service contractors handling residential storm window maintenance.
