StrongJamb™ Armor Plate® Patented 2025
Want to feel safer in your home or apartment—without replacing the whole door frame, in less than 30 minutes? StrongJamb Armor Plate is a recessed 1/4" steel plate.
- Reinforces where it matters most: Strengthens the jamb at the deadbolt and latch—where doors most often split under force.
- More peace of mind: Never placed on the top! Armor Plate resist kicks and prying.
- Cleaner, built-in look: Mortises into the jamb for an integrated, finished appearance.
- Fits common hardware: Machined to accommodate many 2-1/4" residential security bolts and handles.
- Anchors into the framing: Rear holes accept additional 3" (or longer) screws to transfer force toward the structural framing—not the jamb edge.

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!
