It’s sturdy and keeps your window from opening, so you feel safe and secure. The adjustable design works for different window sizes, which is super convenient. Overall, it’s a simple, reliable way to add a little extra peace of mind to your home. Review: Well Made But Should Be a Companion Piece - I used this to secure a vertical window that has a window AC installed. It's well made but I was actually close to returning it because it was just a little too short for my window. The next peg down was too tight and the next peg up was too short. Just then, I realize that you can unscrew the rubber portion at the bottom for micro adjustments. If you can't get a tight fit on your window, you'll want to use the screw near the rubber portion to get it as tight as possible. I do think the bar is probably better suited for sliding glass since it will sit flat on the sill and keep the window from being opened. For vertical windows, someone could just break your window and just push the bar out of the way. I still think it's good to have and extra peace of mind but I would probably go a step further with sash locks in addition to the security bar for extra protection. It will certainly defeat the average dumb crook but if someone really wants in, you'll want more than a bar that can be defeated by breaking the glass. It's still a good product and very well made and sturdy which is why I'm going 5 stars. ## Features - Patent No.D1025743. βœ… STRENGTHEN HOME SECURITY - High-grade Steel window locks security bar block criminals from entering through sliding glass windows or patio doors.

I feel more secure than with another type of bar I tried. Being able to adjust them so the windows are partly open is great. It keeps a person from getting in but my cat can still enjoy nature while watching our bird feeders. I don't use the adhesive or hardware, so prying it out to adjust the holes can be a pain; it appears it could be even with a different installation, but just a guess. Still, the pros far outweigh that con. ## Frequently Bought Together - Jeacent Adjustable Window Security Bar, Patio Door Lock - Sturdy Steel, Extends from 15 1/2" to 29 1/2" - Shop Square Window Locks, 4 Pack Aluminum Thumb Turn Window Lock, Secure Sliding Windows & Doors, No-Drill Install, Child Proof, Indoor Outdoor, Requires 28-36mm Clearance --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/87724965-adjustable-window-security-bar-patio-door-lock-sturdy-steel-extends](https://www.desertcart.us/products/87724965-adjustable-window-security-bar-patio-door-lock-sturdy-steel-extends) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-14*
