## Description

JEACENT AC Security Window Lock Bar, Window Security Bars - Sturdy Steel, Extends from 10" to 17 1/2" for Sliding Windows with AC Unit Installed - desertcart.com

Review: Sturdy and simple for vertical windows. - Used this vertically for a couple windows and it works great and was easy to setup, can be adjusted to allow the window to be open a crack. The adhesion is okay, it's a little pricier than other options, but so far it appears to be good quality.
Review: Secure your double hung windows - Pretty great product. It's easy to install / remove and does what it claims to do. I installed these into double hung windows that were installed incorrectly and couldn't lock as the male and female parts of the lock didn't line up no matter what I tried. I was able to wedge this in between the lower window and lip of the upper window, and when in place my windows couldn't open. This product doesn't have any cons other than the fact that it takes 30 seconds to get the unit fully extended as the locking pin deploys after each 1 hole movement. I see people complaining about the advertised length vs the actual length, but my guess is that they either bought the wrong product (there are two lengths) or they don't know that the screw attached to the rubber stopper can be safely unscrewed partially to reach the advertised max length.

## Features

- ✅ ADJUSTABLE LENGTH - The window lock adjusts from 10" to 17.5" in length. Works well with most standard window tracks with air conditioner installed.
- ✅ SAFER A/C INSTALLATION & PROTECTION - Prevents the window from opening when installing an A/C unit. Keep your window stay in a height to stop your AC unit from falling out or being stolen from outside
- ✅ Sturdy MATERIA - All Steel Construction provides it with a longer longevity and make it harder to break off or deform.
- ✅ NOTICE BEFORE BUYING - Make sure your window track is at least 1 inch wide as this home security bar is about 1 inch wide. The window bar extends from 10" to 17 1/2", please MEASSURE YOUR WINDOW to assure it fits your needs before buying one.
- ✅ QUICK & EASY INSTALLATION - Unique design (patent pending), no tools needed. Held in window track by supplied adhesive strips. Keep your home save and sound.US Patent Pending. All Rights Reserved.

### ⭐⭐⭐⭐ Sturdy and Does the Job for the Price
*by A***X on June 9, 2025*

This window lock bar feels sturdy and worked well in my small window to help secure my window AC unit. It was easy to install and gives some peace of mind. That said, it may not offer as much adjustability or range as some other options out there, so it’s best suited for smaller or more standard-sized windows. Overall, I’m happy with it for the price—it does what I needed it to do and feels solid enough for regular use.
