Your SMART lock is only as strong as the wood it locks into.
With Armor Plate you have No batteries. No wifi. No subscription. But you do have a 1/4 inch of American steel, mortised into your door jamb and anchored to the studs behind it.
Doors don't fail at the lock. They fail at the jamb.
Industry-standard doors and frames are built to save materials - green, and easily manufactured in mass. That is good for the environment and often for energy efficiency. But under a real kick they fail in three to seven seconds. The StrongJamb Armor Plate corrects that necessary but inherent flaw.
Combine your SMART lock with an Armor Plate and get the convenience of electronic locking systems with the surety of a steel barricade at every door.

The people behind the door are the whole point.
Locks and alarms are just means to an end. The end is a family that sleeps through the night without listening for the door.
StrongJamb makes the entry they already trust actually trustworthy - a steel-reinforced jamb that holds when it matters, quietly, for years.
Works with the lock you already trust - even the smart one.
StrongJamb isn't a lock and doesn't replace one - it's the foundation your lock bolts into. It accommodates smart locks and electronic systems better than any competitor, so you keep locking your door from your phone. The Armor Plate just makes the frame worthy of it.

Don't take our word for it. Watch it get hit.

Fifty years of door experience, now protecting doors across Ohio.
Prospeed professionally handled the procurement of a sliding door and 2 sliding windows for my Centerville condo (I am an out-of-town owner) and installed them with me on site. Joe Pollard and his crew performed the work and left the condo in good shape. Greg Pollard made sure I was satisfied. I recommend Prospeed for door and window replacement.
Kim is absolutely one of the greatest people I've ever met. The passion and care that they put into their product is second to none and we are truly blessed to know them.
These guys are amazing! If I could give them 10 stars I would!
Building or remodeling? Ask one question.
Are you reinforcing the jamb, or just the door? Most builders aren't - not because they're cutting corners, but because reinforced jambs have never been standard. Ask while the frame is still open.
