National Mfg N325-381 Rigid Sash Lock Satin Nickel 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N325-381 is a traditional crescent-style rigid sash lock designed for double hung windows. The crescent cam mechanism draws the upper and lower sashes firmly together when engaged, reducing air infiltration and preventing unauthorized entry. Finished in satin nickel, the lock blends with standard residential hardware finishes. This package contains 5 locks, making it practical for multi-window jobs or contractor stock. Installation requires basic hand tools and no special trade licensing, though it is commonly specified by window installers and general contractors on residential projects.

This sash lock is intended for double hung window applications in residential construction and renovation. The traditional crescent profile fits the standard meeting rail on most double hung wood or vinyl-clad windows. The 5-unit pack is suited for new construction window installations, window replacement projects, or hardware upgrades across multiple units in a single dwelling. No specific compatible model numbers or system families were provided by the manufacturer for this listing.

Installation Notes

Sash locks of this type are typically installed by general contractors, window installers, or experienced DIYers using a screwdriver. Before installation or replacement, ensure the window sash is fully closed and the work area is secure. Align the crescent cam to the strike on the opposing sash rail before fastening to confirm proper engagement. Follow local building codes for window hardware requirements on egress windows.
