Engineered with a double locking mechanism and cut-resistant metal, it withstands over 1000 lbs of forced entry tension, making it virtually burglar proof. Its sleek, low-profile design fits discreetly between door frames, while easy DIY installation and child safety features ensure your family stays secure without sacrificing aesthetics. ## Description With young children in the home, you know all too well how hard it is to keep an eye on them at all times. With the Cal Double Bolt child proof patio door lock installed, you can make sure that young ones do not become tempted to open the sliding glass doors on their own and expose themselves to potential danger. The Sliding Glass Door is one of the favorite "break out" spots for children. The closing mechanism is usually a latch, not a lock. This means that it is easier for children to operate than it is for adults to secure. Simply mount the Cal Double Bolt at a height that is unreachable by your children. Another advantage of the Cal Double Bolt sliding door lock is that it is clearly visible whether the lock is engaged or not, so it is more likely that parents will keep it in the locked position. The CAL Double Bolt Lock has a sleek, aesthetic, low profile design. As a result, the sliding glass door lock fits easily within the limited space available between the sliding glass door frame and the interior of the door panel. This amazingly simple device is EASY TO INSTALL and has been tested to provide over 1000 lbs of Forced Entry Load Tension. The Cal Double Bolt patio door lock prevents criminals from being able to lift out sliding glass doors from their tracks. Most factory installed locks or after-market products do not. Criminals know how easy it is to lift a door panel out of its track. Great for parents, grandparents, day care centers, and more. Premium quality metal materials No parts or keys to lose like other locksBlack Color Review: Some hiccups but would buy again if needed - After our sliding door’s plastic casing broke that held the door locked, we purchased this. I was really cautious when installing, measuring 20 times, pre-drilling holes, triple checking over and over again to make sure I didn’t hit the glass in the patio door. Overall, installed, and didn’t break the glass (like other reviews commented). The lock plate that’s on the interior part of the door, not the one attached to the sliding glass, was a little short, so we did use the spacer that came with it, still too short, so we added additional spacers to secure it better. We used spacers that you’d use on electrical outlets when you have tile, like backsplash tile in your kitchen. Worked amazing for that small issue and really secured it! Others commented that the lock bars come apart over time from the bottom/top plastic pieces (see red circles). They did after 6 months maybe. You’re able to push them back in by hand or using a pipe wrench worked best for us. After it continued to separate almost monthly, I used clear Gorilla glue in the holes and since then it hasn’t been an issue (6months ago). I know this sounds like a lot, but I’m still VERY happy with it and would still recommend it and buy again if ever needed. After all said and done, I’m SO GLAD we purchase this cause otherwise the only other option was a new door and to spend money replacing a door that was only 7 yrs old! I’d recommend it, I’m a security freak and feel like this lock is more secure than the lock that came with the patio door. Review: Finally, a secure and childproof lock to fit my friggin door! - Totally worked great on my condo's sliding glass door!!! I live on the ground floor, too, and I'm only too aware of the ease with which break-ins occur through patio doors. My door is entirely too wide for a security bar, and it's not a very hefty frame. It's a very slim metal frame, and I don't have a lot of wall overhang to work with either. To further complicate matters, I have a very curious toddler, and she kept pulling out and hiding the metal pin that was installed on my door when I moved in. She also is tall enough now to open the darn latch, so I really had to step up my game finding a solution for my sliding glass door. I had been looking for MONTHS, literally since I moved in back in April, for something that would secure that door. I have tried a few different things, but had to return them all because they were too bulky for my specific setup, either requiring a thicker frame around the glass, or requiring a deeper inset in the wall. The Double Bolt lock was one of the pricier options, so I was reluctant to try it until my daughter started unlocking the door and I discovered it'd been unlatched for several days unbeknownst to me. After watching the videos and reading the reviews, I was sure that it'd be the answer to my problems. Sure enough, I was able to get it installed in about 20 minutes, and I feel immeasurably less worried about both how childproofed my patio door is, and that it's much, much more secure from intruders! I have given my door a serious tug and really tried to jiggle it, and it feels locked down like Ft. Knox. Love it! It's easy for me to operate, very low-profile, and blends in perfectly with my white patio door. I absolutely am thrilled with it, only wish I'd gotten it sooner -- I could have saved a lot of searching AND slept easier for months! My only quibble is that the childproof lock & key mechanism is kinda cheesy. I can't even get mine to turn without the key bending or the plastic lock trying to strip out, so I don't bother with that part. I installed the lock high enough that my daughter will not be able to reach the top latch for a long time, so it's a minor flaw I have no problem overlooking. The key is simply a flat metal head, like a flat screwdriver, so it would be simple enough for anyone determined enough to unlock anyway, ## Features - CHILD SAFETY: Safeguard your children by preventing them from wandering outside the house. Install the CAL Double-Bolt Lock at the desired height to keep them safe from potential dangers. - HIGH SECURITY: With a tested capacity to withstand over 1000 lbs. of Forced Entry Load Tension, the CAL Double-Bolt Lock prevents criminals from lifting out the sliding glass door from its tracks, providing robust security against forced entry. - SLEEK DESIGN: The lock's aesthetic and low-profile design seamlessly fits within the limited space between the sliding glass door frame and the interior door panel.

Its double locking action prevents unauthorized access and ensures your peace of mind. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0039ONKFQ | | Additional Features | Cut Resistant | | Best Sellers Rank | #53,621 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #90 in Window Locks & Latches #240 in Deadbolts | | Brand | CAL DOUBLE-BOLT LOCK | | Brand Name | CAL DOUBLE-BOLT LOCK | | Color | White | | Control Method | Touch | | Controller Type | Hand Control | | Customer Reviews | 4.5 out of 5 stars 1,108 Reviews | | Finish Types | Powder Coated | | Included Components | CAL Double Bolt Lock + Cover, Latches, Lock Security Key, Screws, Spacers | | Item Dimensions | 11 x 3.5 x 1 inches | | Item Part Number | SafesliderWhite01 | | Item Weight | 8.8 ounces | | Item dimensions L x W x H | 11 x 3.5 x 1 inches | | Lock Type | Deadbolt | | Manufacturer | CAL-TECH International, Inc | | Manufacturer Part Number | CDBL | | Material | Metal | | Material Type | Metal | | Model Name | CAL Double Bolt Lock | | Model Number | CAL-DBLOCK | | Number of Items | 1 | | Number of Pieces | 1 | | Recommended Uses For Product | securing glass sliding doors, preventing burglary, ensuring child safety | | Shape | Rectangular | | Special Feature | Cut Resistant | | Style Name | Double Bolt Lock | | UPC | 781264013165 852411002896 | | Unit Count | 1 Count | ## Product Details - **Brand:** CAL DOUBLE-BOLT LOCK - **Item dimensions L x W x H:** 11 x 3.5 x 1 inches - **Lock Type:** Deadbolt - **Material:** Metal - **Special Feature:** Cut Resistant ## Images ![Double Bolt Lock for Sliding Glass Doors - Newly Patented - Advanced Technology to Keep Your Family Safe and Secure - High Security Lock - Virtually Burglar Proof (White) - Image 1](https://m.media-amazon.com/images/I/41U37QOwXqL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Some hiccups but would buy again if needed *by M***D on January 28, 2026* After our sliding door’s plastic casing broke that held the door locked, we purchased this.

It’s sturdy and works well. We had a little trouble when installing because of the way our door was but we got it figured out. It gives us good peace of mind that our little kids can’t get outside around the pool. ## Frequently Bought Together - Double Bolt Lock for Glass Sliding Doors - Advanced Technology to Keep Your Family Safe and Secure - High Security Lock - Virtually Burglar Proof - Burglabar 2 Pack for Sliding Door Locks for Sliding Glass Doors & Windows, Child Proof - Home Security Door Lock, 2 Pack Childproof Door Reinforcement Lock with 3 Inch Stop Withstand 800 lbs for Top Front Inward Swinging Door, Upgrade Flip High Night Lock to Defend Your Home Kids --- ## 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.ph/products/3087128-double-bolt-lock-for-sliding-glass-doors-newly-patented-advanced](https://www.desertcart.ph/products/3087128-double-bolt-lock-for-sliding-glass-doors-newly-patented-advanced) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-09-10*
