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. ## 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.co.uk/products/475158978-window-locks-4-sets-sliding-security-window-lock-with-key](https://www.desertcart.co.uk/products/475158978-window-locks-4-sets-sliding-security-window-lock-with-key) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
