GarageDoorProject™ Replacement Part - Donkey Cone 2-Piece Garage Door Torsion Spring Winding Tool

The Donkey Cone 2-Piece Coupler is an innovative and essential tool for garage door professionals, designed to convert 4-hole winding cones on 1 3/4" or 2" torsion springs to 8-hole (45°) compatibility. Made from durable 6061 heavy-duty aluminum, the Donkey Cone allows standard 18" winding bars to be safely used in settings that typically require special accommodations, like low headroom or damaged winding cones.

Developed for both efficiency and safety, the Donkey Cone streamlines the spring adjustment process. It enables technicians to apply or release tension on garage door torsion springs without removing or reinstalling top sections, which eliminates the need for makeshift solutions that can cause injury. This efficient tool turns a complex, two-person task into a manageable job for one technician, saving significant labor costs.

SAFE OPERATION: Converts 4-hole (90°) to 8-hole (45°) patterns, allowing safe use of standard 18” winding bars.
VERSATILE APPLICATIONS: Use in low-headroom areas, with damaged cones, back-winding springs, and “cable off” situations.
DURABLE ALUMINUM DESIGN: Made from 6061 heavy-duty aluminum for lasting durability and stability.
COMPATIBILITY: Fits all universal 1¾” to 2” winding cones.
USER-FRIENDLY MARKINGS: Slotted marks on every other hole for easy ¼-turn counting.
