Prime-line Gd12192 Garage Door Extension Spring, 25 In., 120 Lb.

Prime-Line garage door extension springs are heavy-duty replacements designed for residential sectional garage doors up to seven feet tall. These springs work in pairs to lift doors weighing up to 120 pounds, making them ideal for standard two-panel, four-section garage doors. When one spring breaks or weakens, both sides should be replaced simultaneously to prevent uneven door movement and ensure balanced operation.

Extension springs are replacements for worn or broken garage door springs. These Prime-Line springs are rated for 10,000 cycles of reliable operation, providing season-after-season dependability for busy households.
