The QuickFrame 120 is an economical support solution for lighter weight rooftop supports. It’s built to accommodate 1/2″ thread rod, or 1-5/8″ strut off the shelf. This allows for the most flexible solutions and ease of setup. The non-penetrative design spreads out the weight load, keeping the roofing membrane safe and decking/insulation below free of damage. For heavier loads, we recommend the QuickFrame 175.
