Panic Bar with Alarm for Exit Doors with Keyed Entry + External Handle Lock with 6 Matched Keys Exit Device Push Bar Panic Exit Device Lock Key Security Bar Emergency Door Lock

This push bar works great. The alarm, which you can turn on or off, is loud enough to be noticed. However, I received mine missing the battery connector. It looked like they accidentally cut it off during the manufacture process. When I called customer service about it, I asked if they could send a battery terminal connector and I'd just splice it on myself rather than have to return it and wait for a replacement. They weren't able to do that, but they did give me a $10 amazon credit I could use on items sold directly from Amazon and I was able to buy a battery connector with that. This was probably a fluke and likely doesn't happen very often. All in all, even with the hiccup, I'm happy with the product.

No way to get extra keys the seller was absolutely useless
