Always looking forward – Since 1986 With just two of us—Greg, a woodworking craftsman, and Kim, a business manager, We built our reputation restoring historic properties. We loved the work—and learned early on that door jambs have been an after thought! Solving the Universal Problem: Historic commerce or living spaces, seem to treat door openings mostly as a utility. When entryways were meant to impress, fixing them became expensive and difficult for homeowners. In 1999, Greg designed a better way—a custom jamb system that corrects irregular openings and can preserve original doors. Making restoration practical, repeatable, and affordable. We shifted our business to focus on doors and windows,combining standard installations with custom-built solutions for historic homes. Through years of real-world installations and five design iterations, The Original StrongJamb® was born. In 2015, we incorporated as ProSpeed Security Door Jamb Systems, Inc. Our Son Joseph joined as an integral part of the business, and we Trademarked StrongJamb. We kept working through COVID, and family challenges, continuing installations, refining, testing, improving the system. Voila! Armor Plate 2025-PATENTED, STRONGJAMB ARMOR PLATE! THE SON OF STRONGJAMB--A faster, simpler way to reinforce the weakest point in modern door frames. Best of all, Armor Plate maintains esthetics like StrongJamb Full Frame but allows more adjustment and superior security for an after-market security plate.
