Secure, Flexible Protection for Sliding Windows and Doors

PENMAMA 8-pack sliding window locks provide a practical layer of security for homes, apartments, offices, and more. Designed for both sliding windows and sliding doors, this kit combines a screw-in mounting system with durable aluminum alloy bodies and a bright yellow key handle for easy management. Use them to create a controlled opening that preserves airflow and light while adding a reliable barrier against unintended access.

Key fit and compatibility

Each lock is 2.4 inches long and fits tracks up to 0.4 inches wide when cushioned, or up to 0.67 inches without cushioning. For best results, measure your track before installation to confirm a proper fit.

  • 2.4 inch length designed for sliding windows, patio doors, and vertical sliding panels
  • Rubber cushioning helps protect frames and minimize scratches during use

Simple, secure installation

The lock uses a double-screw mounting on the track to prevent unwanted movement. It can be fully secured or left with ventilation as needed, and all installation hardware includes hex keys—no extra tools required.

  • Double-screw design for dependable security
  • Screw-in mounting enables quick setup or removal for cleaning

Durable and easy to spot

Constructed from high-quality aluminum alloy, these stoppers stay sturdy over time. The vivid yellow key handle is designed to be easy to locate, making access straightforward when needed.

  • Aluminum alloy body for lasting strength
  • Bright yellow key handle for quick identification

Versatile use and practical benefits

Ideal for patio doors, sliding glass doors, and other sliding configurations. They offer a balanced approach to ventilation and security, giving you peace of mind when a window is opened a few inches.
