Jamb Wrapping Technology

Door Jamb Armor pieces are sleeves that slide, or wrap, around the jamb and door. This wrapping design provides maximum strength because the jamb is being secured by screws that go through two pieces of steel. It also means that Door Jamb Armor can be used to repair jambs that have been almost completely destroyed.

Wrapping Technology means that Door Jamb Armor requires moderate handy skills to install but nothing is more effective in helping
prevent kick-ins.

Why is wrapping necessary?
When a door is kicked, two types of force are exerted on the jamb:

• Direct force: the straight-ahead force that will tend to push the deadbolt through the back of the jamb.


• Torque: When a door is kicked, it will twist, depending on where it is kicked.

Wrapping technology not only helps deflect the direct force, but also helps prevent the jamb from twisting, which makes it more difficult for the jamb to crack.

Why plates are not as effective.

Our EZ Armor product is a set of L-shaped plates. While it may seem strange to tell you that this product will not be effective, we want to make sure that you understand exactly what you are getting.

• First, in order to make a truly effective strike plate, the plates must be either very thick, very long or both. Any plate thin enough to allow the door to close properly, risks failure when enough pressure is applied.


• Competitive products have been able to make warranty claims because the the lock area on the door will break if enough pressure is applied.


• These plates are only laying against one side of the jamb, which is why they cannot prevent the jamb from twisting when the door is kicked. This causes the jamb to split.


• Jamb Wrapping basically creates a cast for your doorjamb.

• Covering the front and backsides of the doorjamb means that the components need only be half the thickness to produce the same strength.


• By sandwiching the doorjamb on both edges, we insure that the jamb will not move anywhere that the Jamb Shield does not.


• By covering the back edge of the doorjamb, the wood has nowhere to go even if it were to split.

Why is the Jamb Shield so Long?

• The longer length of the Jamb Shield helps absorb the twisting of the door when kicked.


• This longer length spreads the direct force along the length of the stud, instead of allowing it to concentrate in one area.

We applied this same concept to the development of the hinge shield piece. While these pieces are not as long as the jamb shield, they help prevent the jamb from splitting when the hinge side of the door is kicked.

By wrapping the doorjamb, Door Jamb Armor essentially becomes a part of your door from the time you install it.
