Product Description

This left-wind garage door torsion spring is designed for sectional garage door systems requiring a .2187-inch wire size, 2-inch inside diameter, and 45-inch spring length.

Manufactured in the USA from coated, oil-tempered spring wire, it provides dependable lifting performance when correctly matched to the garage door’s weight, height, cable drums, track configuration, and required torque.

The coated finish helps protect the spring surface and reduces the oily residue commonly associated with uncoated oil-tempered springs.

The winding cone and stationary cone are already installed, making the spring ready for professional installation after all specifications have been verified against the original spring or a properly engineered spring calculation.

Common Uses

This torsion spring may be used in properly engineered spring systems for:

• Residential sectional garage doors
• Light-commercial overhead doors
• Single-car and two-car garage doors
• Workshop and storage-building doors
• Standard-lift garage door systems
• Single-spring torsion systems
• Two-spring torsion systems

The 45-inch spring body may be used where the door’s weight and required torque call for this specific spring size. The additional spring length must not be treated as automatically interchangeable with a shorter spring using the same wire size and inside diameter.

Actual compatibility depends on a complete spring calculation, not only the garage door’s width, height, or appearance.

Compatibility & Fitment

This torsion spring is compatible only with garage door systems engineered for all of the following specifications:

• .2187-inch wire diameter
• 2-inch inside diameter
• 45-inch spring body length
• Left-wind configuration
• Compatible torsion shaft and cone bore
• Correct cable drums
• Correct track and lift configuration
• Correct torque requirement for the garage door’s weight

Correct spring selection depends on:

• Actual garage door weight
• Garage door height
• Cable drum model
• Track configuration
• Standard-lift, high-lift, or vertical-lift setup
• Number of springs in the system
• Wire diameter
• Inside diameter
• Spring body length
• Required inch-pounds per turn
• Intended cycle life

Do not select a replacement spring based only on door dimensions, mounting position, color markings, or visual similarity.

Important Matching Notes

A left-wind torsion spring is commonly installed on the right side of the center support bracket when viewed from inside the garage facing the closed door. Spring placement can vary depending on the torsion-system design.

Always verify wind direction from the spring itself instead of relying only on its installation position.

Measure the spring body only after all tension has been safely removed. Measure the wound coils from end to end without including the winding cone or stationary cone.

The spring wire should be measured by counting and measuring 10 or 20 coils and dividing by the number of coils. Measuring a single coil with a tape measure may produce an inaccurate result.

A spring with the wrong wire size, inside diameter, length, or wind direction may prevent the door from balancing properly and can overload the opener, cables, drums, bearings, or other garage door hardware.

When replacing one spring in a two-spring system, verify the size, wind direction, age, and condition of both springs. Replacing both as a properly engineered matching pair may provide more consistent balance and service life.

Installation Notes

This spring includes the winding cone and stationary cone. It does not include:

• Winding bars
• Torsion shaft
• Center bearing
• Center support bracket
• End bearing plates
• Cable drums
• Lift cables
• Bottom fixtures
• Mounting fasteners

Before installation, inspect the torsion shaft, bearings, cable drums, lift cables, brackets, bottom fixtures, and attachment points for wear, corrosion, deformation, or damage.

After installation, disconnect the automatic opener and test the garage door manually. A correctly balanced door should move smoothly and remain near the halfway-open position without rapidly rising or falling.

The correct number of winding turns and final spring adjustment must be determined from the door height, cable-drum configuration, spring engineering, and manufacturer requirements.

Safety Warning

Garage door torsion springs store extreme mechanical energy. Improper removal, installation, winding, or adjustment can cause severe injury, death, or property damage.

Installation should be performed only by a trained garage door technician using correctly sized solid-steel winding bars and established safety procedures.

Never use screwdrivers, ratchets, socket extensions, rebar, or improvised tools to wind or unwind a torsion spring.
