SSC .2253 x 1.75″ ID x 27.5″ Torsion Spring – Left Wind – Red

🇺🇸 Made in USA

Manufactured by Service Spring Corporation (SSC), this .2253″ wire x 1.75″ inside diameter x 27.5″ left-wind torsion spring is intended for sectional door systems specified for this spring configuration.

Supplied with winding and stationary cones installed, the spring uses coated, oil-tempered wire. Correct sizing is essential to provide the counterbalance torque required for controlled door movement.

Features & Benefits

• .2253″ wire diameter with red wire-size identification.

• 1.75″ inside diameter.

• 27.5″ unwound spring-body length, excluding cones.

• Left-wind configuration.

• Installed winding and stationary cones.

• Coated, oil-tempered wire.

• Stenciled and color-coded for identification.

• Standard-cycle spring listed for a minimum 10,000-cycle application when correctly selected.

One opening and closing equals one cycle. Actual lifespan depends on operating turns, loading, maintenance, installation, and corrosion exposure.

Specifications

Common Applications

For replacement of a matching spring on a compatible sectional overhead door. Suitability depends on door weight and height, cable-drum specifications, track configuration, and the complete spring arrangement.

Door width or opener horsepower alone cannot establish compatibility.

Compatibility & Measurement

Confirm .2253″ wire diameter, 1.75″ ID, 27.5″ unwound body length, and left-wind direction. Verify cone and shaft fit, stationary mounting, and operating clearance.

Do not confuse this spring with a .2253″ wire spring having a 2″ ID and a similar length. Inside diameter is a separate, essential measurement that affects spring performance.

The red wire-size marking must not be confused with cone markings used to indicate winding direction. Identify winding direction from the spring configuration, not the wire-size paint alone.

Pairing & Higher-Cycle Options

On a two-spring door, both springs must provide the correct combined output. A same-size right-wind companion is appropriate only when that pair matches the door’s engineered requirements.

Some installations use intentionally unequal spring sizes. Have the existing arrangement and both springs evaluated when replacing a failed spring.

Higher-cycle alternatives require a calculated replacement that preserves the required operating characteristics and fits the available shaft space. High-lift, vertical-lift, and drum changes require separate calculations.

Installation & Safety

Professional installation is strongly recommended. Torsion springs and connected hardware store enough energy to cause severe injury.

Do not loosen loaded cones, drums, cables, or bottom brackets. A trained technician should follow the door manufacturer’s procedures, verify balance throughout travel, and check cable tracking and opener safety reversal before normal operation.
