The PRIME LINE PRODUCTS F 2554 is a white window sash lock designed for securing double-hung windows in residential and light commercial applications. Built with cam action engagement, it draws the sash tightly closed for a firm, consistent seal. Alignment lugs aid in proper positioning during installation, reducing misalignment common in older or replacement window frames. The diecast construction provides solid, repeatable locking performance. This part is typically installed by glaziers, general contractors, or experienced maintenance technicians handling window hardware replacement or new construction finishing work.
The F 2554 is suited for double-hung window applications where a standard sash lock is required. The white finish coordinates with most painted or vinyl window frames common in residential construction. It ships in a package quantity of six units, making it practical for multi-window jobs or stocking service vehicles. The cam action mechanism is a widely used locking style in wood and vinyl double-hung windows across residential housing stock.
Designed as an OEM-style replacement sash lock for standard double-hung windows requiring a cam-action locking mechanism with alignment lugs.
Installation is performed by carpenters, glaziers, or maintenance technicians familiar with window hardware. Before beginning, ensure the window sash is fully closed and the work area is secure. Use a screwdriver sized to the existing mounting holes and verify alignment lug seating before final fastening. Follow all applicable local building codes for window hardware replacement.
