Product description

Colour Name:Brushed Chrome

Add an extra layer of security to your home with this U 11325 door reinforcement lock. Designed to withstand 800 lbs. of force, you can rest easy knowing your family is safe and protected! This reinforcement lock has a spring-loaded design, aluminum construction and a brushed chrome finish. This brushed chrome reinforcement lock can be quickly and easily installed on any swing-in door of any thickness, and can help ensure the door cannot be opened from the outside by being kicked in. Additionally, it’s tamper-resistant, so it can protect against lock picking and bumping. Plus, it’s child-safe, because you can install it higher on a door, where your young ones can’t reach. Installation takes minutes, and the U 11325 door reinforcement lock comes with 3” hardened screws. Extra home security and peace of mind are well within reach - and doesn’t have to come with the high price tag of an alarm system! This high security door lock meets the Texas building code requirements. Be sure to view the manufacturer’s How-To Installation Video also linked to this page, in the upper left hand corner.

1.0 out of 5 stars False Security - A Pointless Exercise
Reviewed in the United States on 9 June 2020
The screws provided are so soft they fail DURING INSTALLATION! Look at the picture! That is what happens when you try to screw this into a 2 x 4 stud - - complete failure. The screws are far too soft to withstand the torque needed to get them into your studs.

In fact, the entire device is made of this same ultra soft, ultra cheap steel. This product is "eyewash" or "eye candy" for those who want security, but have no expertise. It is so cheaply made it is not worth the time and bother to install it. Yes, they fooled me. But ONLY ONCE!

I bought two, and they are being returned immediately as rubbish!
