Product details
Description
- [Bar for Security] If you are concerned that your windows and doors aren't sturdy enough or you feel it is unsafe when travelling alone, AceMining's door jammer security bar will offer you a complete peace of mind with only one easy-to-use but distinctive lever which is also easy to install.
- [2-in-1 Door & Sliding Door Security Bar] Use our adjustable door security bar to deter burglars from breaking into your house, apartment, or even hotel room. The length of the door barricade security bar can be adjusted from 21 to 46inch, and the full product weighs only 2.2 pounds, making it easy to carry during travel or store at home.
- [Easy to Use] The AceMining door brace security bar is very simple to use, has a three-stage structure, and can be quickly deployed. This allows you to quickly strengthen your defense. However, while using it, you must be careful to ensure that there are no gaps between the rubber foot and the ground.
- [Versatile and Enhanced Design] The lock bar is equipped with enhanced high-strength alloy connections to extend the service life. It also features thickened 1.57inch pipe diameter design, high-quality material upgrades and plastic components made of high-strength fiberglass material making it stable and sturdy. Since the security bar on an AceMining door stopper can endure 400 pounds of force, an invader would have to be as strong as a heavyweight boxer to open the door.
- [Customer Service] AceMining provides 20 months customer services. If you run across any issues or face any problem with the sliding door lock, please get in touch with us. Bring extra security for your loved one’s home without delay.
- [Attention] Although AceMining Door Security Bar may not 100% effective at preventing entry on some situations, it would absolutely provide enough time to either prepare for the intrusion or alternatively flee the area.
