National Mfg N151-225 Zinc Window Bolt 2 Inches

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N151-225 is a 2-inch zinc window bolt designed to secure sliding or double-hung windows against unauthorized entry or accidental opening. The bolt slides into a strike mounted on the window frame, providing a positive mechanical stop that keeps the sash in the closed or ventilated position. Mounting screws are included, so no separate hardware is needed for installation. At 1.3 pounds per package of 10 units, this bolt is a standard restocking item for residential window hardware jobs.

This window bolt is suited for residential applications where a simple, low-profile locking solution is required on wood or vinyl windows. It is commonly installed by general contractors, carpenters, and maintenance technicians during new construction, renovation, or window hardware replacement projects. The zinc construction resists corrosion in typical interior window environments. Each unit ships carded, making it practical for retail display or jobsite parts organization.
