Enhance your window safety with STERGDE Sliding Window Locks. These robust aluminum locks are designed to withstand daily use while remaining simple to install without drilling. The included keys and thoughtful design bring a sense of control to the way you open and ventilate spaces.

Designed for versatility, they fit a wide range of vertical and horizontal sliding windows commonly found in homes, apartments, hotels, and offices.

Compatibility at a glance

• Works with many vertical and horizontal tracks; confirm fit by measuring height and width

Key features that matter

• Thickened aluminum alloy delivers durable, deformation-resistant performance
• Two fixed holes maximize mounting stability for stronger security protection
• Widened lock body provides a solid blocking area when the window is partially opened
• Protective washer guards the window surface from scratches during operation

Easy to install without drilling makes it a convenient option for many spaces: place, insert the protective spacer, and tighten the screw. The set includes four locks, four mounting hex keys, four protective gaskets, and one vertical key suitable for center-track mounting. The design supports reconfiguration by using either a vertical or hex key for different positions, so you can adjust as your setup changes.

In real-world use, these locks offer flexible control over how far a window opens, helping to keep children or pets safe and reducing opportunities for intrusion. They are lightweight, compact, and color-matched in silver, blending into many interiors while offering peace of mind—without promising guarantees, but with practical benefits you can assess in your own space.
