SSC .2830 x 1.75″ ID x 120″ Torsion Spring – Left Wind – Light Blue

🇺🇸 Made in USA

Manufactured by Service Spring Corporation (SSC), this .2830″ wire x 1.75″ inside diameter x 120″ left-wind torsion spring is a long-length product for professionally specified counterbalance applications.

Its coated, oil-tempered wire and listed 120-inch body distinguish it from the shorter finished replacement springs commonly used on sectional doors. Confirm the intended use, supplied configuration, and required finished spring dimensions before ordering.

Features & Benefits

• .2830″ wire diameter with light-blue wire-size identification.

• 1.75″ inside diameter.

• Listed spring-body length: 120″, equivalent to 10 feet.

• Left-wind configuration.

• Coated, oil-tempered wire.

• Winding and stationary cones listed as installed.

• Stenciled and color-coded for identification.

• For applications with professionally calculated spring requirements.

Specifications

Cycle Life

The listing states a standard minimum 10,000-cycle classification. For this long-length product, cycle suitability must be confirmed for the actual finished configuration, loading, and working turns.

Length alone does not establish a higher-cycle rating or guarantee compatibility with an existing door. One cycle consists of one complete opening and closing.

Compatibility & Intended Application

Verify .2830″ wire, 1.75″ inside diameter, left-wind direction, and the required finished length. The 120-inch measurement describes the listed spring body, not a door-height or weight rating.

Determine whether the application requires the full listed length or a separately specified custom assembly. Do not assume this product is a ready-to-install equivalent for a shorter .2830″ wire spring.

Check cone fit, shaft compatibility, stationary mounting, and installation clearance, including the cones and the spring’s length change during winding.

Pairing & Engineering Considerations

Spring selection must account for door weight, height, cable-drum geometry, lift configuration, operating turns, and companion springs. The complete assembly must produce the required torque throughout the door’s travel.

A 2″ ID spring is not automatically equivalent to this 1.75″ ID version. High-lift, vertical-lift, and drum changes require a separate calculation.

Any proposed modification must be evaluated and performed by a qualified spring professional. Changing spring length changes torque per turn and the resulting counterbalance.

Installation & Safety

This specialized spring should be handled and installed by a trained garage door technician or qualified spring professional. Torsion springs store enough energy to cause severe injury.

Never loosen loaded cones, drums, cables, or bottom fixtures. The completed installation must be checked for manual balance, cable tracking, operating clearances, and safe opener performance.
