Overview:

Door Closers: It's a portable, industrial-strength door security device that prevents unwanted entry. It takes just moments to fit to any standard internal door without the use of any tools. Once fitted, it uses the displacement of force to barricade the door against an attempt at forced entry. Please note that it does not apply to carpets and the like; please be aware before buying.

Designed for Commercial Use—Created for emergency deployment in public buildings, schools, offices, or hotels—this is the last word in portable stopping power.

The Hardest Material: After years of research, we have produced this product. Small but very hard material. Don't worry about your safety; it can firmly hold the door. In case of emergency, you can easily remove the door brace with an upward motion.

Easy to Use: Whether you are an adult or a child, you can use it easily. Position the door blocker with the bottom flange under the door, directly below the door handle. Adjust the foot so the door stopper is tightly fitted. Test the door to make sure the door stopper is securely positioned.
