Engineered from solid aluminum and heavy-duty steel, it resists over 1,000 lbs of forced entry without batteries or wiring. Its anti-lift metal-to-metal framework and flexible child-safe mounting make it a top-tier security upgrade that’s both virtually invisible and highly effective. ## Description The CAL Double Bolt Lock is a heavy-duty, surface-mounted mechanical deadbolt system manufactured by CAL-TECH International, Inc. It is explicitly engineered as a high-security aftermarket upgrade for residential sliding glass patio doors and windows. By establishing dual-point metal-to-metal contact, the lock anchors the active door panel directly into the frame. This mechanical design effectively stops intruders from prying the door open or lifting it entirely off its tracks. ## Features - Lock Style: Surface-mounted, dual-point mechanical deadbolt. - Forced Entry Resistance: Tested and certified to withstand over 1,000 lbs. of Forced Entry Load Tension. - Material: Solid aluminum construction complete with heavy-duty steel locking bolts and a weather-resistant hard-paste finish. - Locking Action: Dual interlocking steel rods extend vertically into a heavy-gauge frame retainer. - Power Requirement: 100% mechanical (Non-electric design requiring no batteries or wiring). - Net Unit Weight: 0.28 lbs (approx. 4.5 ounces). - Anti-Lift Protection: Its metal-to-metal interlocking framework prevents criminals from exploiting the common vulnerability of lifting sliding panels straight up out of their lower tracks. - Flexible Child-Safety Mounting: Because it is entirely independent of existing handles, it can be mounted high up on the frame wall—well out of reach of toddlers—to prevent unsupervised pool or patio access. - Low-Profile Aesthetics: Engineered to seat flat within the tight, narrow channel between the sliding glass glass panel and the interior door frame, making it practically invisible when look-through visibility is preferred. - Available Color Finishes: Distributed in Midnight Black, Pearl White, and Gun Gray/Silver to blend naturally with standard architectural vinyl or aluminum frames. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MT1GIXC | | Batteries required | No | | Best Sellers Rank | #808,609 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,258 in Window Locks & Latches | | Customer Reviews | 4.4 4.4 out of 5 stars (141) | | Is Discontinued By Manufacturer | No | | Item Weight | 5.6 ounces | | Item model number | CAL001 | | Number Of Items | 1 | | Product Dimensions | 11.9 x 1.5 x 4.5 inches | ## 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 2-Pack) - Image 1](https://m.media-amazon.com/images/I/61U+1NsrbuL.jpg) ## Frequently Bought Together - CAL Double Bolt Lock - Sliding Patio Door Locks - Child Proof Sliding Door Lock with Anti Lift Security Lock - Replaces Sliding Door Security Bar - Adjustable & Fits Most Doors (White) - EUDEMON 4 Pack Baby Safety Door Knob Covers Door Knob Locks(not Suit for All Door knobs) --- ## 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.ec/products/43760327-double-bolt-lock-for-sliding-glass-doors-newly-patented-advanced](https://www.desertcart.ec/products/43760327-double-bolt-lock-for-sliding-glass-doors-newly-patented-advanced) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-22*
