About this item

  • KEEP YOUR HOME SAFE – Designed to withstand 800 lbs. of force, this U 11449 matte black finish door reinforcement lock helps to prevent inswing doors from being kicked in, increasing your home security and keeping you and your family safe!
  • EASY INSTALLATION – The included 3” hardened screws make installation a breeze – extra security and peace of mind can be achieved in just minutes. Watch the video on this page for installation tips and operating instructions.
  • ADDITIONAL HOME SECURITY – Use this high security door reinforcement lock for additional home security on any swing-in door of any thickness. It helps to ensure any door cannot be opened from the outside.
  • CHILD-SAFE AND TAMPER-RESISTANT – The spring-loaded design can be installed at a higher level, to ensure it is child-safe. Plus, while locked, this tamper-resistant door latch protects against the door being kicked in, lock picking and bumping.
  • PRE-DRILLING – The included 3 inch security screws require holes to be pre-drilled with 1/8 inch drill bit. Do not use a drill driver with max torque setting to install the 3 inch screws as you can strip or break the heads. Some doors may require mortising. Additional mortising may be required to fit your door.
  • NOTE - You may wish to purchase the MP114498 high security finger pull, designed to make opening this lock easier

I've used this item for several years now, I love the level of safety it provides and peace of mind. It's also great if you have kids that are able to open the door and great for doors that have access to pools if you have young kids

Noticed other brands “broke” and became hard to open after a short time. Hard to believe since this is a simple mechanism. Anyway bought these because there has been no issues like that reported on this brand (which is what sells for more in big box stores).Gave a lower rating for install, but there’s not much that can be done. It’s not a design or manufacturing flaw. You have to chisel out a bit of door frame and fiddle a little to get it to function right. Can’t really be helped. Not the products fault. So to install u need to be a little handy and a little patient.Other reviews mentioned the quality of the screws. This is true. I was able to get them to work by pre-drilling, but still, one star off for something so easy to fix. Include better screws please.Will change review if they suddenly become hard to unlatch.

My wife has been getting a littler paranoid about adding more security to our doors, she use to lean a chair on our back patio door for more security so I decided to install a new lock, after looking for a while see the style that was not bulky and simple to install so orders 2 for front and back door. I tested them and they secure the door firmly so no more dragging a chair to lean against it. You can even lock it during the day as well. Most importantly I found them cheaper looking at returned items and paid 60% of what a new one will have cost. They are working great and will recommend anyone to install them.
