4-Pack Sliding Sash Window Stopper Lock – Child Safety & Anti-Theft Security Limiter for Cabinet Doors

Protect your family and secure your home with this 4-Pack Sliding Sash Window Stopper Lock Set. Engineered for sliding glass windows, patio doors, and cabinet track systems, these compact security limiters restrict window and door opening widths—preventing young children and pets from accidental falls while deterring unauthorized entry from the outside. Crafted from high-strength, impact-resistant ABS polymer and equipped with durable stainless steel internal components, each stopper withstands repeated forceful pushes without cracking or slipping. The intuitive dual-wing wedge design allows for smooth, tool-free installation: simply peel the heavy-duty self-adhesive backing, apply to a clean frame, and flip the wings up to lock or down to allow full sliding movement. Its slim profile fits discreetly inside standard window tracks without obstructing regular opening clearances when disengaged.
