Designed for horizontal sliding vinyl windows and many single-hung vinyl windows, this adjustable lock helps secure windows in the closed position or partially open for controlled airflow. It serves as an effective secondary security device without requiring permanent modifications to the window. The adjustable jaw features a vise-like grip that securely clamps to vinyl window rails while helping prevent damage to the frame. The cam-style locking lever tightens easily by hand, allowing for quick installation and adjustment without tools. Compatible with rail thicknesses ranging from 1/16 in. to 1/2 in., this lock provides versatile fitment for a wide range of vinyl window applications. Constructed from durable diecast metal with a white painted finish, this window lock is built for reliable everyday use while blending with most vinyl window frames. Whether used to enhance window security or maintain a safe ventilation position, this lock offers a simple and dependable solution. Verify rail dimensions before purchasing to ensure proper compatibility. From the Manufacturer This sliding window lock is constructed of diecast and comes in a white painted finish. This lock is DESIGNED FOR USE ON HORIZONTAL VINYL SLIDING WINDOWS, yet it may also work with some vertical sliding (single hung) windows, depending upon the type of vinyl liners and balances used to construct the windows. Note: These locks will fit most all horizontal vinyl sliding windows and some vertical sliding windows, but not all of them. These locks feature an adjustable jaw that has a “vise-like” grip, and they are capable of opening up to 1/2 in. wide for a secure, non-marring hold on thick vinyl rails. When installing this lock, the cam style locking lever should be rotated hand-tight over the rail or vinyl edge to a sufficient torque prior to locking down the lever. This lock can be adjusted to fit on rail thicknesses ranging from 1/16 in. to 1/2 in. thick. This lock can be used as a secondary lock when window is shut and to secure the windows during ventilation. For a larger version of this lock (used on vinyl frame patio sliding doors) see model number U 10547. No tools are required for installation. ## Features - Ideal Use: Adds secondary security to horizontal sliding vinyl windows and many single-hung vinyl windows while allowing controlled ventilation - Dimensions & Compatibility: Adjustable jaw fits vinyl frame rail thicknesses from 1/16 in. to 1/2 in.; designed for vinyl windows only - Materials & Components: Durable diecast construction with a white painted finish and cam-style locking lever - Key Features: Vise-like gripping action secures firmly to the window rail without requiring tools, drilling, or permanent modifications - Fit Guidance: Hand-tighten the adjustable jaw before locking the cam lever; verify rail thickness and window compatibility prior to ordering ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005H3N43K | | Additional Features | Adjustable | | Best Sellers Rank | #17,471 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #16 in Window Locks & Latches | | Brand | Defender Security | | Brand Name | Defender Security | | Color | White | | Customer Reviews | 4.3 out of 5 stars 4,600 Reviews | | Finish Types | White | | Global Trade Identification Number | 00049793098092 | | Included Components | Window lock | | Item Dimensions | 1.19 x 1 x 20 inches | | Item Highlight | Easy Installation, Keeps Windows Securely Closed, Diecast Construction | | Item Type Name | Sash Lock | | Item Weight | 4.48 ounces | | Item dimensions L x W x H | 1.19 x 1 x 20 inches | | Lock Type | Rim Lock | | Manufacturer | Prime-Line Products (Home Improvement) | | Manufacturer Part Number | U 9809 | | Manufacturer Warranty Description | Goods are warranted against manufacturing defects for 1 year. | | Material | Diecast | | Material Type | Diecast | | Model Name | Sliding Window Lock | | Model Number | U 9809 | | Number of Items | 1 | | Number of Pieces | 2 | | Recommended Uses For Product | Securing windows in residential or commercial buildings | | Shape | shape | | Special Feature | Adjustable | | Style Name | Sliding Window Lock | | UPC | 049793098092 | | Unit Count | 1 Count | ## Product Details - **Brand:** Defender Security - **Item dimensions L x W x H:** 1.19 x 1 x 20 inches - **Lock Type:** Rim Lock - **Material:** Diecast - **Special Feature:** Adjustable ## Images ![Prime-Line Sliding Window Lock for Vinyl Windows, White, Diecast, 2 Pack | Easy Installation, Keeps Windows Securely Closed, Diecast Construction - Image 1](https://m.media-amazon.com/images/I/510ipgXxLoL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Can I use this product in sliding doors?** A: U 10547 is the door version of this item **Q: How does it work? Are you going to post any pictures of it in use?** A: They work great. Seems like it would be easier to break a window than to try to force a window that is locked with two of these. Simply twist them until they begin to tighten to window frame, then clamp them down. They tighten the rest of the way when you clamp them, a lot like vise grip pliers. I'm adding two photos to help. **Q: does this come with 2 pcs in a pack? or this is only fr 1 unit?** A: Luckily, I saved a packaged pack for back-up. The USB on it says 0 49793 09809 2, and it is indeed a 2-pc packet (which states "Fits 1" wide rail"). The cam locking mechanism also makes re-placing the lock easy. **Q: is this somthing that can keep my 6yr old from the window all the way or could it be easly removed by him** A: That seems like a loaded question. When I was 4, I figured out how to put a kitchen chair next to the counter. Climb on the counter and hoist myself to the top shelf of the cupboard to retrieve a bottle of Flintstones vitamins. I subsequently ate the whole bottle and had to have my stomach pumped. Kids are smart. Nothing is completely kidproof. Having said that, it depends on the type of window. Does it slide left to right or up and down? Mine slide up and down, and a child would have to be tall enough to reach high enough to unlatch them. ## Frequently Bought Together - Prime-Line U 9809 Sliding Window Lock for Vinyl Windows – Easy Installation to Keep Windows Securely Closed – Diecast Construction, White (2 Pack) - Toddleroo by North States Sliding Window & Door Wedge Locks | Limits The Space That Windows and Sliding Doors can Open | No Tools Required | Baby proofing with Confidence (4-Pack, White) - 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 --- ## 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.ma/products/3743406-prime-line-sliding-window-lock-for-vinyl-windows-white-diecast](https://www.desertcart.ma/products/3743406-prime-line-sliding-window-lock-for-vinyl-windows-white-diecast) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-09-13*
