What Is a Garage Door Cable Drum?

Garage door drums come in different sizes based on the door’s height and the lift it requires. Residential garage doors typically use standard hubs, while commercial ones often require keyed hubs.

Drums work alongside the spring system to counterbalance the door, while cables provide the lifting mechanism. The cables, attached to the door’s bottom corners, wind around the drum as the door opens and unwind as it closes. Malfunctioning cables or drums can lead to uneven or jerky door movements.

Types of Garage Door Cable Drums

Garage door cable drums come in three main types:

Standard-Lift Drums

These have flat grooves, with slightly raised edges to maintain balance while the door opens.

Vertical-Lift Drums

Taller than standard drums, these keep the cable farther from the shaft when the door is closed. As the door opens, the cable winds closer to the shaft.

High-Lift Drums

These combine features of standard and vertical-lift drums, allowing the door to open vertically before transitioning to the horizontal track.

Why Do Cables Slip Off the Drums?

Garage door cables can slip off the drums for various reasons:

Damaged Torsion Springs

If one or both springs break, the cables lose tension and may unwind, causing the door to crash down. Avoid using the door and contact a professional immediately.

Obstructions

Malfunctioning safety features, such as auto-reverse mechanisms or photo safety eyes, can cause the door to hit objects, slackening the cables.

Improper Spring Tension

Springs with too much or too little tension can cause cables to jump or unwind from the drum.

Incorrect Cable and Drum Sizes

Heavier doors require thicker cables and larger drums. Using the wrong size can strain components, leading to premature failure.

How to Replace Garage Door Drums and Cables

Replacing garage door drums and cables is a complex and hazardous process that requires specific tools and expertise. Here’s an overview of the process:

Preparation

Ensure the door is fully closed and resting evenly on the ground. Use winding bars to release tension from the springs safely.

Cable Removal

Loosen the screws on the drum and detach the cable from the bottom bracket.

Cable Installation

Attach the new cable to the bottom bracket and thread it up toward the drum, ensuring it runs between the tracks and rollers. Wind the cable onto the drum and adjust tension as necessary.

Final Checks

Ensure even tension across both sides of the door before testing its manual operation.

Given the complexity and risks, it’s highly recommended to hire professionals like Garage Door Repairs for this task.
