After years of shimming hollow metal door frames, as recommended by door manufacturer instructions, and not being satisfied with the results we developed a better solution. The patent pending JambJack design solves the issue of jambs sagging after installation, especially the hinge side. Jambs can move after installation due to careless abuse during construction and shim removal by flooring contractors. After the heavy commercial doors are installed you can be left with difficult door fitment issues to resolve. If you've hung commercial hollow metal KD DW door frames then you understand how important it is to get it right the first time!
John has spend over 30 years in the commercial door and hardware installation business. During this time he's learned what does and doesn't work when it comes to proper door and frame installations. The JambJack is the direct result of his desire to build it better.
Tim is a friend and former co-worker with John who also has some experience in design, manufacturing, and sales. He loves solving problems and has a passion for building better. Construction is in his blood, and the JambJack is our idea to help make it better.
Please contact us if you cannot find an answer to your question.
The JambJack is designed to pinch and hold a typical 16GA hollow metal frame. It can be also be opened with a screwdriver to fit a 14GA heavy duty frame, or closed with pliers or a hammer for a lightweight 18GA frames.
Full metal construction and threaded fasteners can easily support a jamb during and after installation. In combination with a frame's standard wall attachments the JambJack can help support the heaviest of commercial doors.
We will be selling direct through this website in the near future and we are always looking for distributors and wholesale opportunities.
