PENMAMA Window Locks - 12-Pack Sliding Window & Door Security Locks with Key

Secure, versatile window locks for everyday peace of mind

When you want a steady breeze without leaving windows wide open, PENMAMA Window Locks offer a balanced solution. They work with horizontal sliding windows and vertical doors, making them suitable for homes, offices, and patios. The 12-pack provides flexible security for multiple openings, so you can secure several windows or doors with a consistent, easy-to-use system.

Key advantages at a glance:

• Two-screw, screw-in design provides secure mounting and easy ventilation when needed.
• Rubber cushioning protects frames and glass during adjustments and everyday use.
• Durable aluminum alloy body with a bright yellow key handle for quick identification.
• Includes 12 locks with cushions and keys to secure multiple openings.

Easy to install and adjust

Each lock is 2.4 inches long and fits tracks up to 0.4 inches with cushioning, or up to 0.67 inches without cushioning. Measure your track first for a proper fit to ensure smooth operation and reliable security.

The hardware is designed to stay put while still allowing controlled ventilation. The screw-in design means a secure hold, and rubber padding reduces scratches during installation and use.

Quality you can rely on day after day

Made from sturdy aluminum alloy, these locks feel robust in hand and offer lasting performance. The yellow key handle stands out, making it easy to locate in a drawer or bag, even on a busy morning.

Real-life use cases

• Keep a bedroom window secured during the night while a few inches stay open for air and alertness.
• Secure a patio door to deter unauthorized entry while allowing safe, filtered ventilation.
• Apply multiple locks to several windows in a home or office for flexible security.

With 12 pieces in the pack, you have the flexibility to secure multiple openings at once, or to swap locks between rooms as needed.
