For older exterior door
LaurensDad gave Armor Concepts 5 stars
My kitchen door was kicked in a couple of years ago, and I cobbled together a mediocre fix. Then I came across this jamb reinforcement for 1-3/8" door, which mine was. Ordered it and it arrived quickly. Super easy to install and nicely covers old damage. I couldn't find any hinge or lock reinforcements for thinner doors, so just replaced hinge screws with longer ones. Very neat installation, highly recommended.
