Green Hinge | 4 Panel 1-Stall Garage Door (Under 12' Wide) - Silver Springs | Weather Sealing Garage Door Hinges | Options for 4–7 Panel Doors | 12-Gauge Steel | Made in USA - GarageDoorProject

Green Hinge System | Professional Garage Door Sealing Hinges for 4 Panel Garage Doors | Silver Springs For Doors UNDER 12 feet wide | Energy Saving | Heavy-Duty 12-Gauge Steel | Made in USA -- GarageDoorProject proudly offers the Green Hinge System — the most advanced, energy-saving hinge system ever designed for residential overhead garage doors. This patented spring-loaded hinge replaces traditional center hinges and creates a tight, automatic seal every time your door closes. By eliminating air gaps and stopping drafts, the Green Hinge System helps maintain garage temperature, protect stored items, and reduce energy costs year-round. Unlike weatherstripping that cracks, shrinks, and needs constant replacement, the Green Hinge System adjusts automatically and maintains a lifelong seal — even on uneven floors, misaligned tracks, or slightly warped door panels. This makes it the only self-adjusting, gap-eliminating hinge system engineered specifically for residential garage doors. Built from heavy-duty 12-gauge powder-coated steel, each hinge delivers commercial-grade performance while providing quieter, smoother door operation. Perfect for homes, workshops, heated garages, and hobby spaces. Installation is simple: Replace only the center hinges — never the top or bottom brackets. Single Stall Doors under 12' wide will have silver springs. Double stall garage doors 12' and wider - choose the commercial product which has gold springs. 4-panel systems use 6 hinges, 5-panel systems use 8 hinges, 6-panel systems use 10 hinges, and 7 panel systems use 12 hinges (See image diagram for proper hinge placement.) With lifelong durability, Made-in-USA construction, and a true Lifetime Warranty, the Green Hinge System offers unmatched performance, comfort, and value.

• SELECT THE RIGHT FIT: For heavy-duty or commercial applications (12' wide and over), choose the "Commercial" model featuring Gold springs. For standard home use (UNDER 12' wide), select the "Residential" model featuring Silver springs. GarageDoorProject exclusively partners with US vendors, ensuring 100% OEM parts with all-new production dates.
• COUNT YOUR GARAGE DOOR PANELS: Choose the correct number of panels. The "panels" are the individual sections that make up your complete garage door. You can count them by looking for the breaks/seams between the solid sections. Each solid section is a "panel".
