This lock comes in two shades, including satin nickel and polished brass, and has been designed by a former member of a SWAT team. With the assistance of a drill, it's stated that a typical installation will take only minutes, and besides doors made of glass and other delicate materials, this lock can be attached to nearly any door.

How to Use (Step by Step)

  1. Choose Location for Lock

    Before you can start the installation process, you'll need to choose an ideal location on one of your doors for this lock. Keep in mind that if a door won't accommodate screws, because it's made out of glass or a similar type of material, it's not a door that this lock should be attached to. When it comes to the exact location of your lock, placing it higher rather than lower is usually better. However, you may want to lower it if you'd like children to be able to use it.

  2. Attach Latch to Doorframe

    Next, it'll be time for you to attach the first part of your FlexStrong Lock (one of two), the latch, to your door. To get started, mark three drilling holes on your doorframe and then use a 3 / 32 drill bit to guide the three included 1.5-inch screws into the appropriate holes within your latch. Following that, use the drill to guide the screws into the holes on your doorframe, and this will attach the latch to the frame. For more specific advice and tips pertaining to this entire step, you should consult your instruction manual.

  3. Attach Hook to Door

    Once your latch is fully attached, you'll have to attach the hook piece to your door (not the frame). Line the hook up horizontally with the latch, and make sure you can close the latch over the hook. After that, mark four drilling holes in your door that correspond to the holes on the hook, and then use your drill bit to guide the four included 0.75-inch screws through those holes. Once again, for tips and assistance, you can consult your instruction manual while you're completing the hook-attachment process.

  4. Use Lock to Secure Door

    When your lock's latch and hook are both attached to your door with screws, you'll be able to use the lock to secure your door. Open your latch up until you hear a click, then close the door. Push down on the latch's release button and then cover the hook with the latch.

How It Works

Unlike standard door locks, the FlexStrong Lock contains a rubber cushion that will absorb shocks and then snap itself back into place, thereby keeping your door locked against potential intruders. That means if an intruder decides to aggressively pound or kick your door with their body or an object, it's unlikely that this type of lock will ever allow them to get the door open. On the other hand, with a standard door lock that won't absorb shocks as this one does, a determined intruder may be able to break it by punching or kicking and gain entry.


  • Two Shades Available

    When you decide to get a set of FlexStrong Locks, you'll be able to obtain a set in satin nickel (silver) or polished brass (a gold-bronze shade). Each lock in a silver set will actually be made from nickel, while the gold-bronze locks in a set will be made from brass. If you don't have a personal preference for either shade, you may want to choose the one that'll look best with whatever doors you want to use these locks on.

  • Come in Sets of Three

    These locks come in sets of three, so you can use a set on your back door, front door, and side door, or three different doors at a place of business, if you'd like. As alluded to above, all three locks in a set will necessarily come in the same shade, so if you want both nickel and brass locks, you'll have to get two sets.

  • Strong and Durable

    Every FlexStrong Lock is made of strong, high-quality material. In fact, each one is purported to be 750 times stronger than a standard lock plus a deadbolt on a door. The strength of these locks means that each one may last you for years, even if you move one or more of them from one door to another at some point.

  • Lightweight

    You might expect a lock like this to be heavy since each one's so powerful, but each one only weighs about a pound. Furthermore, when they're connected together, the combination of the two pieces (latch and hook) will only measure about four inches. As a result, if you ever have to transport these locks from one location to another, they won't be bulky to carry or take up a lot of space. You might actually be able to carry one in a large pocket.

Positive Points

  • Helps Protect Family, Business

    If you've got children or other vulnerable family members at home, or lots of valuable items in your business office, this lock can give you some extra security and peace of mind. Once you install one of these, you should be able to relax while you're away from your home or workplace, as there's almost no chance anyone will get in while you're away. If anxiety has been an issue for you in the past, you won't have to constantly fret about your family members or your valuables being harmed during a break-in.

  • Compatible With Most Doors

    The FlexStrong Lock is compatible with most doors, regardless of their height, width, or thickness. If you can use screws to attach the two separate pieces to the door's material, you'll be able to use this lock on that door. Consequently, if you move to a different home or office, or get new doors installed, you'll likely be able to transfer this type of lock to the new doors without an issue.

Negative Points

  • Drill Required

    Those potential users who aren't good with a drill might think twice before installing this type of lock on a door since a drill is required for installation. It's stated that the installation of one of these locks will take just minutes, but that's assuming that you're fairly skilled with a drill. If you're not, installing this kind of lock could take much longer and become frustrating.

Critical Advice

You should always use the screws included with your FlexStrong Lock to attach it to one of your doors. If you were to use screws of another type, the lock could become loose and stop keeping people out. In the event that you ever lose a screw and you need a replacement, be sure to replace it with a screw of the exact same size as the original one to avoid this problem.
