We are StrongJamb
We are a professional contracting, family business called ProSpeed, based in Dayton, Ohio, specializing in customizing, securing and replacing doors and windows for over 35 years. Home contractors turned inventors, to fix some of the inconsistencies and industry standard weak links of the door frames that we were improving or replacing. ProSpeed Security Door Jamb Systems, Inc. was developed during those years of trial and error, until we had a system that will insure proper installation, provide high level security, aesthetically beautiful and versatile, affordable, and systematic. It matters that we have an affordable way to keep our homes in good repair, safe and looking good. StrongJamb products make that happen. Please check out our Armor Plate and StrongJamb security system. Thank you!
