Baldwin premium sash locks are crafted from 100% solid forged brass, offering a construction that is significantly stronger than standard hardware. These heavy-duty window fasteners feature a spring-loaded mechanism that provides constant tension to reduce drafts and ensure a non-rattling fit. Finished in polished brass (030), these locks provide a timeless look for traditional double-hung windows. Each unit comes sealed in its original packaging with the necessary mounting screws included for easy installation.
