I don’t recommend them for your 5th wheeler windows **Q: Will this work on single hung window** A: Yes it does on single hung winows **Q: will this work on vinyl windows?** A: Just barely with mine....be sure to measure the height of your track frame and depth of the track it will sit on and in...compared to the depth/width of the keys. They have held in place so far to prevent slider window from being pushed open past the setting of the key. **Q: what is the screw diameter?** A: Not sure how to estimate that. I wasn't really sure either. Give it a try. ## Customer Reviews ### ⭐⭐⭐⭐⭐ My little man strikes again. *by A***Y on October 6, 2024* My kid got one of the windows in his room out of it’s track. He had to also break a latch off the window to get to where he could remove the window. It’s a miracle the glass didn’t break. I don’t know how he was able to break the latch and I couldn’t get it back on of course.You may be wondering why I didn’t stop him from doing it in the first place. I was watching the Vikings paste the Giants in New York, even though the stadium is in East Rutherford New Jersey. Go Vikings.Now that he knows how to take it out I had to immobilize the window somehow. The short term solution was to use a vice grip to jam the window closed. Does the kid know how to use a vice grip? No, but I bet he can figure it out! Long term solution is these clamps. They come with Allen wrenches with wings that make instillation super easy. He watched me do it so as long as I keep the wrenches away from him he 𝑝𝑟𝑜𝑏𝑎𝑏𝑙𝑦 can’t get the window out again. I think it’s worth noting that this same child once pulled a doorknob off a door without removing the screws. Seriously. The doorknob was in another room but the screws that hold it in place were still in the door. At least he didn’t lose anything we needed to put it back together.This product served my purpose very well. There is foam on the inside to prevent metal on metal contact but once tightened it stays securely in place. For my situation these were worth every penny. ### ⭐⭐⭐⭐⭐ Great window locks! *by M***P on August 17, 2025* My 6 yr old son is non-verbal and has autism. That has not stopped him from opening the standard window lock and opening the windows to get on the roof of our sun room. These locks work as advertised and being able to use a key has stopped him from trying to open the windows. ### ⭐⭐⭐⭐⭐ Easy to install *by R***M on July 27, 2025* This worked like a charm. After installing a portable A/C, my wife wanted a piece of mind to prevent anyone from opening the window from the outside om being open and these window locks gave that to her. I installed one at each side. The installation was very easy! ## Frequently Bought Together - Window Locks, 4 Sets Sliding Security Window Lock with Key for Vertical & Horizontal Sliding Windows & Sliding Doors, Adjustable Window Locks Security Window Stoppers for Patio Bedroom Home and Office - ZRFCXE Window Locks,4 Pack Sliding Window Locks With Key for Vertical & Horizontal Sliding Windows Doors,Easv to Install,Adjustable Security Window Lock for Patio Bedroom Home and Office (Black) - DIIG Sliding Door Security Bar，17.7-50.5inch Adjustable Locking Window Safety Bar with Rubber Tips,Diameter 1inch Window Security Bar for Home Apartment Travel (White) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/344547268-window-locks-4-sets-sliding-security-window-lock-with-key](https://www.desertcart.in/products/344547268-window-locks-4-sets-sliding-security-window-lock-with-key) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-18*
