EQLEF2 Pieces Gray Iron Sliding Door Safety Lock & Sliding Window Stopper

Easy to put in place. Can block the sliding door from opening if your cat tries to open it but not strong enough for a human!

Had great hope for these. But sadly they did not fit our sliding wardrobe.

After reading awful reviews of the hotel we were visiting regarding break ins I bought a one of these for each room, very easy to install had zero issues
