*** ATTENTION: PROPERLY COUNT YOUR GARAGE DOOR PANELS & IDENTIFY THE WIDTH OF YOUR DOOR (it is quite simple!): Hinge Kits are SPECIFICALLY DESIGNED for the type of door you are working on. "Panels" indicate how TALL your door is by counting the sections of the door from bottom to top where they separate as the door rolls up. Each solid section between gaps is a single "panel". Count all of them to identify your total panels. Identify the WIDTH of your garage. Kits are engineered with specific spring strengths based on how WIDE the door is. 1-car garage vs. 2 car garages. 1-car garages are UNDER 12 feet wide. 2-car (with one door) garages are 12 feet up to 20 feet wide. ***All Heavy Duty Commercial / Industrial doors should use the "2-Car Wide" version (with Gold Springs) of your panel count regardless of actual door width due to the extra weight of the door. *** DO NOT ATTEMPT TO SPLIT A "KIT" BETWEEN TWO OR MORE DOORS (it will not work) - Hinges are not all identical. Each one is NUMBERED for its specific location on your garage door as the gap between the door and vertical track increases as you get higher on the door. Therefore, you CANNOT use a 7-panel kit between two 4-panel doors. ENERGY-SAVING GAP SEAL Hinge System automatically seals side gaps to minimize drafts, enhance thermal efficiency, and lower heating/cooling costs. DURABLE 12-GAUGE STEEL Heavy-duty powder-coated construction provides strength, smoother operation, and reduced rattling for residential doors. PATENTED AUTO-ADJUST DESIGN Spring-loaded hinges maintain constant pressure, creating a tight seal even on uneven floors or slightly warped garage doors.
