At first this didn’t seem to work, but then realized I just needed to read the directions. It works great!

This item was purchased to replace another one That is malfunctioning.

Can’t make this security bar exactly fit my sliding door track. Pre-made holes make it too short and easy to knock out of the track. Still looking for a security bar like the one I bought years ago, which has a screw in mechanism, allowing you to set a specific length that does not change. It also has a bracket that screws into the door so you can lock the bar in place. This one is good if you plan to use it on a lot of different doors and you require adjustability.

We use it for our patio door, works great!

Best for door knobs. Works great on tile. But is shorter for most of the sliding doors.

First time using curbside and the lady that brought it out to me could not have been any nicer. Appreciated her kindness.

Did not hold at the bottom

Very secure door back up for the locks.

Easy to use and gives an additional layer of security.

Very sturdy would be great for added security on the front door

Doesn’t work on a smooth wood floor. So it’s a safe bet not on tile either. No carpet in the house, so not sure if it would work that way.
