Segal4764 Fixed Window Guard – Adjustable Child Safety Window Guard Prevents Accidental Falls, Tamper Resistant Screws Included, Non-Egress, White, 23-1/2 to 38 In. W x 21-1/4 In. H (Single Pack)

Heavier than expected. The sliding feature allowed it to fit my garage window perfectly.

My house is set up in such a way that all of the windows are easily visible to both of my neighbors and to passers-by on the street, so that anyone who tries breaking into my home when I'm not around will be readily seen. All, that is, except for one particular bedroom window I have near the back of the house, which is blocked from neighbor/street view by a storage shed, and is at ground level (one-story home). I saw this as a glaring weak point in my home's security, and this window guard was EXACTLY what I needed to fix it.I had this thing in place and mounted in less than 10 minutes total. The screws that are included with this are one-way screws of questionable strength and quality, and I didn't want to chance running one halfway in and then having it get stuck or snap off and having no way to back it out, so I used my own. Just stuck the assembly up in place, pre-drilled holes in the window frame, and then ran some heavy-duty 3-inch screws into the studs (Camo brand screws, which are VERY strong and use Torx bit heads). DONE!This guard is VERY secure and will certainly deter most any smash-and-grab punk that tries to target my home for stealing stuff to sell for drug money. No home security is theft-proof, but as of right now, the only way someone is getting into my place easily is if they decide to tunnel underneath and cut a hole in the floor to get inside, or they just use a chainsaw to cut a hole in the back wall. LOL

The expansion is of ease, sturdy, and strong.

This thing was a little hard to install, but I blame that more on our weird, annoying window than the product itself. Our 2nd story bedroom has a window that is for some reason very close to the ground. It opens outward on a vertical axis using a hand crank, and has a lock that flips up and down like a light switch. So the challenge was to figure out how to install the guard in such a way that the hand crank and window lock can still operate unimpeded by the guard bars, without leaving a big gap underneath the bars, which would negate the entire purpose. It took a couple tries and the bar spacing made it tricky, but we eventually figured out a setup that, while perhaps not the ideal configuration, is the only one that works for our weird window. And all that really matters is if it does the job of improving safety for our toddler, which it does.As other commenters have suggested, we used our own screws instead of the provided “permanent” ones so that it can be uninstalled someday. It’s still very secure.Overall I’m happy with this purchase. The peace of mind it brings is well worth any frustration during installation.

I am pleased with this product. The delivery was swift, and I was able to install it in less than 5 minutes without any difficulty. However, it's worth noting that the screws are not like regular Phillips or any other type. I accidentally rounded two of them and had to replace them with new screws since the product does not include any tools to help with this new screw format. I'll purchase three more guards; however, while I understand why the vendor has chosen this type of screw, it would be helpful if they offered the appropriate tool to go along with it.

I am a contractor I used 8 of these guards for me client which they were 54 inch wide it fit perfectly screwing to window frame was breeze less than a minute. I forgot to take pictures which I will when I visit my customer, highly recommend

Used it on my back door, screen door. Everyone kept using their butt to hold open door and pushed screen in. This adjusted to the screen opening and works great. Well made, heavy duty.

Bars are fine for a low expectation of security use. A battery powered saw can cut them quickly. My real complaint is the quality of the screws. These are not very good and the heads stripped readily. I am going to buy better ones locally.
