Prime Line Left-hand Wind Garage Door Replacement Torsion Spring, .243 X 1-3/4 X 32 In., Red, 1-pk.

This Prime Line GD 12229 left-hand wound torsion spring is designed to replace broken garage door springs that match its specific dimensions. Garage door torsion springs provide the lifting force necessary to operate heavy garage doors. Selection of the correct replacement spring depends on matching the precise dimensions rather than the door's weight.

This replacement spring features a .243-inch wire size, 1-3/4-inch inside dimension, and 32-inch length, all color-coded red for easy identification. The spring comes pre-mounted with both stationary and winding cones to simplify installation. In dual-spring installations, both left-hand and right-hand wound springs must be correctly installed during the same job to ensure balanced operation.

Features and Benefits

• Pre-Mounted Cones: Includes stationary and winding cones already installed for faster setup and reduced installation complexity.
• Left-Hand Wind Design: Specifically wound for left-side mounting (mounted to the right of center when viewed from inside the garage looking out) in dual-spring systems.
• Dimension-Based Selection: Sized by wire thickness, inside diameter, and length rather than door weight, ensuring a proper match to your existing spring.
• Complete Replacement Solution: Comes with all necessary cones pre-mounted for efficient installation.

Safety

These garage door torsion springs can cause serious injury if not handled and installed properly. All broken or malfunctioning hardware should be replaced with matching hardware of identical dimensions without any modifications. When dual springs are present, both the left-hand and right-hand wound springs must be installed together. The use of winding rods is required for replacement. Before ordering, verify that this spring's dimensions match your existing spring exactly.
