SSC .2187 x 2.00" ID x 27" Torsion Spring – Left Wind (LW) – White

🇺🇸 Made in USA

This Left Wind (LW) torsion spring is manufactured by Service Spring Corporation (SSC) for sectional overhead door torsion systems requiring a .2187" wire size, 2.00" inside diameter, and 27" spring length.

Manufactured from coated, oil-tempered spring wire, this spring comes with the winding cone and stationary cone installed and is rated for an industry-standard minimum lifecycle of 10,000 cycles.

The .2187" wire size uses the White DASMA color code. Color should be used only as an identification aid—always verify the actual wire diameter, inside diameter, spring length, wind direction, and required spring specifications before ordering.

Specifications

Application

Designed for torsion-spring counterbalance systems on sectional overhead doors where the calculated spring requirements call for a Left Wind .2187" x 2.00" ID x 27" torsion spring.

This spring may be used in residential or light commercial sectional door systems when its torque characteristics correctly match the door weight, height, cable drums, track configuration, and overall counterbalance design.

Compatibility & Fitment

Torsion springs are not universal replacement parts.

Correct replacement requires matching or properly recalculating:

• Wire diameter

• Inside diameter

• Spring length

• Wind direction

• Door weight

• Door height

• Cable drum type

• Track configuration

• Number of springs

• Required torque and IPPT

• Available shaft and spring space

Two springs that appear similar can produce significantly different torque and should not be considered interchangeable without proper spring calculations.

Left-Wind Identification

This is a Left Wind (LW) torsion spring.

On a conventional torsion system, a left-wound spring is typically installed on the right side of the center support when viewed from inside the garage looking toward the door.

Spring systems can vary, so always verify the actual wind direction rather than selecting a spring based only on its position.

White Wire Color Code

The White color code identifies the .2187" wire size.

Do not select a replacement spring based on color alone. Paint markings can fade, become dirty, or be confused with other markings.

For accurate replacement, physically verify:

• Wire size

• Inside diameter

• Unwound spring length

• Wind direction

Important Matching Notes

When replacing one spring in a two-spring system, inspect and identify the opposite spring as well.

Paired torsion springs normally use opposite wind directions, but the two springs are not necessarily identical in every application.

Changing wire size, inside diameter, or spring length changes the spring's torque characteristics. A different-size spring should only be substituted after the door's counterbalance requirements have been properly calculated.

Cones Installed

This spring is supplied with the winding cone and stationary cone already installed.

Proper installation requires correctly sized torsion-spring winding bars and knowledge of:

• Spring winding

• Shaft positioning

• Cable drum setup

• Cable tension

• Bearing alignment

• Door balancing

After installation, the complete door should be tested for proper cable seating, drum alignment, spring balance, smooth travel, and correct counterbalance.

Safety Warning

⚠️ Torsion springs operate under extreme stored mechanical energy and can cause severe injury, death, or property damage if improperly installed, adjusted, or removed.

Installation and service should be performed only by a qualified person familiar with torsion-spring systems and using proper tools and procedures.

Never loosen a winding cone, stationary cone, cable drum, bearing plate, or related torsion-system component while the spring is under tension unless you understand the correct service procedure.

If you are unsure whether this spring is correct for your door, verify the existing spring specifications or have the replacement spring professionally calculated before ordering.
