3-7/8 in. Hinged Bar Lock, High Security Door Guard, Diecast Zinc Construction, Satin Nickel Plated FinishThis swing bar door guard will increase peace of mind when answering the door by allowing the door to be cracked open slightly for viewing. When engaged, a ball on the keeper interlocks with the bar lock and prevents an intruder from pushing their way through. Although a standard swing bar door guard can add great security to your home, condo, apartment flat, or hotel room, there has been some concern over the wide availability of emergency release

This swing bar door guard will increase peace of mind when answering the door by allowing the door to be cracked open slightly for viewing. When engaged, a ball on the keeper interlocks with the bar lock and prevents an intruder from pushing their way through. Although a standard swing bar door guard can add great security to your home, condo, apartment/flat, or hotel room, there has been some concern over the wide availability of emergency release tools, which are meant to release swing bar door guards in cases of emergency. We have improved upon the standard door guard design and added an innovative backup thumb turn security lock that blocks the release tool from disengaging the door guard latch. In cases of emergency, hotel security or emergency crews can pop the thumb turn off of the unit by applying approximately 100 pounds of force to the door. ( note that 100 lbs. Of force is much greater than a simple kick in, so the emergency release feature does not compromise your security.) additionally, after the thumb turn lock breaks away, the unit still operates as a traditional swing bar door lock and a specially designed Anti-Lockout emergency access tool is required to swing the door guard out of place. To help prevent forced entry into your home, it is always a good idea to engage the backup thumb turn lock whenever you are not actively using your door. Defender Security by Prime-Line offers a full line of security hardware designed to protect your home and loved ones.

Sturdy, Easy to Use, and Great for Privacy
Color: Black, Size: 88" W, Color: Black, Size: 88" W
This room divider is exactly what I needed! The metal frame feels very sturdy and stable, and the wider bases keep it from tipping over easily. The fabric provides great privacy and blocks light much better than expected. I also love how lightweight and foldable it is, making it easy to move around or store when not in use. Assembly was simple and only took a short time with the included instructions. Overall, it looks great, feels high quality, and works perfectly for creating a private space at home. Highly recommend!

Not bad
Color: Grey, Size: 88" W
Claims to be non see through but you can, easy to assemble but instructions aren't good. Decent money value, quality is okay. Good fit, not very sturdy.

Lighter Than Expected — Perfect for My Garage Workspace!
I just received this room divider and haven’t had a chance to set it up yet, but I’m already impressed. It’s much lighter than I expected — I was worried it would be bulky and unstable, but that doesn’t seem to be the case at all. It feels easy to handle and still solid enough for what I need. I plan to use it in my garage to section off a small workspace, and it looks like it’s going to work perfectly!
