Product: Heavy Duty Security Door Bar | Fully Adjustable, Universal Door Stopper Device for Home Defense | Perfect for Residential and Commercial Use to Protect Against Forced Entry by SecuraDoor
Brand: SecuraDoor
Color: Satin anodized gunmetal gray with medium gray accents
Description: Protection Against Forced Entry

Research shows that most burglars enter through the front door… and alarm systems only alert you when someone has broken in. They can’t prevent intruders. SecuraDoor will help keep you and your loved ones safe and secure in your own home.

In the workplace, SecuraDoor is an effective part of an Active Shooter/Lockdown Protocol. It can also be used in schools on any in-swinging doors.

Unlike other door braces on the market, SecuraDoor is easy to use and guaranteed for life… thanks to its patented design and quality craftsmanship. The engineered handle, unique collar design and footplate can withstand over 1-TON of force on any type of floor. It turns any room into a "safe room," giving you a greater sense of security.

SECURADOOR HAS BEEN INDEPENDENTLY TESTED at Westpak, Inc, San Diego, CA, a UL Registered Firm, ISTA Certified Laboratory and an A2LA (American Association for Laboratory Accreditation) Accredited Mechanical Testing facility.

US Patent Number D823664
1.HOME SECURITY: Weighing just over 3lbs, our door bar is made of heavy-duty aluminum alloy and durable thermoplastic elastomer. Our door stopper is more than 5x STRONGER than the leading brands. Over 1-TON of strength, independently tested by a UL registered firm and ISTA certified laboratory. Quick and easy installation on doorknob heights 34" to 48" with hinged doors that open inward. No damage to your door or floors! Great for use in homes, apartments, dorms, office and traveling!
2.HOW IT WORKS: Simply install the security bar between the floor and the interior doorknob of any hinged door by adjusting the length of the door stopper. The unique handle rotates providing compression to hold your door securely in place for security against forced entry. Our adjustment collar allows for easy insertion of the adjustment pin and smooth travel of the inner tube. Our handle yoke allows for easy one-handed installation on any doorknob while protecting your hardware’s finish.
3.HOW WE ARE DIFFERENT: We offer the only door security brace that can adjust to all doorknob heights in accordance with the International Building Code. Our footplate provides maximum surface contact and the highest level of adhesion with any type of floor surface including carpet, vinyl, tile, concrete, and hardwood. The rotation of the footplate is designed to provide optimum support strength angle when installed, as opposed to a ball-joint that can slip out of place due to lateral movement.
