Purchased this to secure a 2nd door. Once receiving it I realized it was heavy duty and stronger than the one Ive owned for years. Will be purchasing another.

amazing product

The price, assembly, and look are well worth it! It is easily knocked over to the side (by the vacuum robot), but it holds up pretty well if you try to open the door.

Guard Dog Security Bar

The Dog Security bar is sturdy and easy to use. We tried and were unable to open the door with this in place. It's also easy to move when you are ready to go out.
