ZhouDaShu 4-Pack Adjustable Window Lock Bar – 9.8 To 16.7 Inch, Steel Security Bar For Small Vertical Sliding Windows, Child Safety & Burglar Deterrent

About This Product

These ZhouDaShu window security bars are a simple but effective way to keep your home safer.
You get 4 adjustable bars in the pack, and each one extends from 9.
8 inches up to 16.

7 inches, with 7 different length settings to choose from – just push the pin to lock in your desired size.
They're made from quality steel, so they're way more durable than cheap plastic or PVC alternatives, and they can take repeated impact without bending.
Perfect for small vertical sliding windows or even dog doors.

They let you keep windows partially open for fresh air or AC airflow while preventing kids or pets from falling out, and they also stop intruders from sliding the window open.

Installation is mostly tool-free: for horizontal sliding windows, just place the bar in the track; for vertical windows, you'll need to attach it to the frame with tape or screws (not included, but easy enough).

Just make sure your window track is at least 1 inch wide before buying.

If your windows are bigger, they also sell longer models (16.

3 to 29.

3 inches) in the same store.
Solid peace of mind for not much money.
