Featuring an innovative backup thumb turn lock that prevents unauthorized emergency release, it allows safe ventilation while securing your entryway. Easy to install with included fasteners, this door guard is a trusted choice for homes, condos, and vacation properties seeking reliable secondary locking protection. ## Description This swing bar door guard will increase peace of mind when answering the door by allowing the door to be cracked open slightly for viewing. When engaged, a ball on the keeper interlocks with the bar lock and prevents an intruder from pushing their way through. Although a standard swing bar door guard can add great security to your home, condo, apartment/flat, cabin, vacation home, hotel room or motel room, there has been some concern over the wide availability of emergency release tools, which are meant to release swing bar door guards in cases of emergency. We have improved upon the standard door guard design and added an innovative backup thumb turn security lock that blocks the release tool from disengaging the door guard latch. In cases of emergency, hotel security or emergency crews can pop the thumb turn off of the unit by applying approximately 100 pounds of force to the door. ( note that 100 lbs. Of force is much greater than a simple kick in, so the emergency release feature does not compromise your security.) additionally, after the thumb turn lock breaks away, the unit still operates as a traditional swing bar door lock and a specially designed Anti-Lockout emergency access tool is required to swing the door guard out of place. To help prevent forced entry into your home, it is always a good idea to engage the backup thumb turn lock whenever you are not actively using your door.

After marking where the screws needed to be, I used a hammer and a long nail to make holes in the marked areas. Then I pulled the nail out after each hole was made. After that, I was able to use screws to attach the lock pieces. The lock is still firmly in place and works great. **Q: entry is double door with one side always closed - can the U-11317 be used?** A: It is a decision you would need to make. The mounting screw length is 1 3/4" for the side you would use to mount on the inactive door. You do not want the screws to go through your door vs. it being installed on a door jamb frame. **Q: My door frames are very thin. What is the width of the smaller piece that goes on the frame?** A: The swing arm has to get screwed in the 2x4 studs behind the frame. **Q: Seems this could be improved if the thumb lock was spring loaded? similar to the door reinf lock; particularly if you're trying to keep someone in** A: The lock is not designed to keep anyone inside. They are designed to keep someone from getting in and still allow you a small view of the other side of the door. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid material *by U***A on 18 February 2024* Recommend to buy ### ⭐⭐⭐⭐⭐ Good for additional safety *by L***N on 4 September 2023* Durable material and good for additional safety ### ⭐⭐⭐⭐⭐ Very durable *by V***D on 3 November 2022* Great swing bar guard for extra door security. --- ## 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.za/products/267764590-defender-security-u-11317-swing-bar-door-guard-with-high](https://www.desertcart.co.za/products/267764590-defender-security-u-11317-swing-bar-door-guard-with-high) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-05-30*
