National Mfg N148-684 Window Sash Lock Bright Brass 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N148-684 is a bright brass finish window sash lock designed to secure single- and double-hung windows in residential applications. Constructed from die cast zinc, this sash lock delivers solid hardware performance in a classic bright brass finish that suits traditional window trim. Each package includes the mounting screws needed for installation. The lock is sold in a pack of five units, making it practical for multi-window projects or contractor restocking. This is a straightforward mechanical lock intended for installation by general contractors, carpenters, handymen, or experienced DIYers.

This sash lock fits typical residential window sash applications where a standard cam-style lock is required to pull sash rails together and secure them in the closed position. The bright brass finish coordinates with period-appropriate or traditional hardware on wood or vinyl double-hung windows. It is commonly used during new construction, window replacement, or hardware upgrade projects where multiple windows require consistent, matching locksets.

Key Features

• Die cast zinc construction for solid, consistent hardware performance
• Bright brass finish suits traditional and period-style window trim
• Includes mounting screws for a complete, ready-to-install package
• Pack of 5 units supports multi-window installations and contractor use

Compatibility

Designed as an OEM-style replacement or upgrade sash lock for standard residential single- and double-hung windows accepting a conventional cam-style sash lock.

Installation Notes

Installation is performed by a general contractor, carpenter, or qualified handyperson using a standard screwdriver. Close and align both window sashes fully before marking and drilling pilot holes to ensure proper cam engagement. Do not overtighten mounting screws, as die cast zinc hardware can crack under excessive torque. Follow local building codes where window hardware security requirements apply.
