Prime-Line U 9899 Swing Bar Lock for Hinged Swing-In Doors – Secondary Security Lock for Door & Security, 3-7/8” Bar Length, Diecast Zinc Construction w/ Antique Brass Finish (Single Pack)

I purchased the Defender Security 10308 Hinged Swing Bar Lock a while ago for added security on my home's front door, and I must say that I'm very satisfied with the product. My maintenance man kept knocking on my door and not giving me enough time to answer the door before barging in on me so this was a impulse purchase based on circumstances.The lock is made of heavy-duty steel and has a solid construction, making it very durable and reliable. The installation process was straightforward and easy, and the included screws and hardware made the job simple.What I really like about this lock is its hinged swing bar design, which allows me to easily swing the bar into place and secure the door from the inside. The lock is also adjustable, which is great for doors of different thicknesses.Once installed, the lock provides an extra layer of security and peace of mind. The bar is easy to swing into place, and it provides a sturdy barrier that prevents the door from being opened from the outside. The lock is also easy to disengage from the inside, so it doesn't impede my ability to exit in case of an emergency.Overall, I would highly recommend the Defender Security 10308 Hinged Swing Bar Lock to anyone looking for added security for their doors. It's an affordable and effective solution that provides peace of mind and added protection for your home.

This door lock is solid. For less than 10 dollars you can buy peace of mind, it's an excellent value for the money. My door edge is not flat, but rounded and it still installed without a problem. Fits relatively flush and works as intended. Sturdy and strong. Buy it.

The media could not be loaded. Bought this for added security especially we have kids at home. Husband bolted it on our door. Material is awesome quality, it’s easy to use, performance is great, it’s easy to maneuver. Overall great quality for money!

Got one previously on ebay and it broke. Cheapness. This one is legit. Easy to install, great hardware.

The installation process isn’t the clearest, so read the directions carefully. Also, pay attention to the measurements of your door frame. They provide two plastic shims, which were just enough to bring the two pieces level for me, but there are probably many doorframes that it wouldn’t work on.So far, it’s working well. Thankfully it hasn’t been fully put to the test, but it definitely does its job when I forget to unlock it before opening the door.

It was a bit tough for me to put these in, only because I have metal frames. Wood frames will be no trouble. I feel very safe having these on my doors. The look very nice on the doors and have a sturdy thickness to them. That's exactly what you want when looking for something that will fit your needs. They are very durable and give me peace of mind. It took a bit of adjusting to get it to fit just right, but once I did everything came together smoothly.

Easy to install so happy my purchase now I can sleep

Swing bar door guard feels and looks heavy duty. Instructions were straightforward. Diagram was especially beneficial. You can’t miss when you follow the sequence and required distance measurements. Also used a leveler tool to ensure mounting flanges’ wider sides were at a right angle so as to correctly align movable loop to the arm. My door and jamb were both hardwood, so I switched to a 1/8in drill bit. Still needed the help of a power screwdriver to fully get screws in to be well mounted.
