Description: Upgrade your home security with our Super Heavy Duty Security Door Wood Grain Lock Bar. It weighs just over 3 lbs and is made from strong wood. It provides more than 5 times the strength of the leading brands, and it offers more than 1-TON of strength. Independently tested by a UL-registered firm and ISTA-certified laboratory, it will protect your home from forced entry like no other. Quick and easy to install on doorknob heights ranging from 34" to 48", this door bar is ideal for hinged doors opening inward and won't damage your door or floors, making it ideal for homes, apartments, dorms, offices, and even while traveling. Why Choose Us: We stand out as the only door security brace on the market that adjusts to all doorknob heights as dictated by the International Building Code. Our patented rotating handle creates compression for a tight fit while still allowing the adjustment collar to be operated easily. The footplate is specifically designed to provide maximum surface contact to any floor surface, from carpet to vinyl to tile to concrete to hardwood, without slipping. Unlike any other product using ball-joints that tend to move laterally, our door stopper design ensures the strongest support angle. With an Unlimited Lifetime Guarantee behind it, you can count on our product for lasting security.
