Exact-match spring review
Suggested from wire candidate, inside diameter, relaxed length, wind, door weight, drums, track, and spring count.

Step 1
Start with the situation.
Create a local project record. No account is required for the free beta.
Project details
Tell us who is using the tool and what the door is doing.
Stop and keep clear: Do not operate or force a door with a broken spring, loose cable, off-track roller, hanging section, or unstable movement. Springs, cables, drums, cones, and bottom brackets can release stored energy.
Step 2
Show the whole setup.
Stay on the floor when possible, use camera zoom, and keep hands and tools out of the spring/cable area.
Required identification photos
The frame turns green when resolution and lighting are usable. It does not approve the repair.

Evidence only: green confirms resolution, lighting, and sharpness. It does not identify the object, diagnose the door, or approve a repair.
NEEDEDNEEDEDNEEDEDNEEDEDNEEDEDNEEDEDNEEDEDNEEDEDNEEDEDNEEDEDStart with the full header photo. The app will not assume a standard torsion setup from a close-up.
Step 3
Measure. Then cross-check.
A direct ruler reading is the primary measurement. A known-size object is only a secondary photo reference because perspective can distort scale.
20-coil wire-size check
Measure the length of 20 consecutive coils. Do not enter the danger zone or move, unwind, loosen, or remove hardware to obtain a reading.
Wire-size candidateWaiting for measurement
NOT READY10,000-cycle baselineAt four full cycles per day, that is about 6.8 years of theoretical cycle use. Actual life varies with system design, installation, environment, balance, and maintenance.
The result remains a candidate until the photos, inside diameter, length, wind, door weight/configuration, drums, track, and cycle target are reviewed.
ENGINEERING ESTIMATE
SUPPLIER / PRO VERIFYDoor balance and spring-rate check
Uses your measured wire candidate, inside diameter, spring body length, door height, and spring count. Add the weighed door and verified effective drum radius.
Austin field baselineSelect door width and construction above to compare a common starting configuration. Never order from this reference alone.
Total torqueWaitingDoor weight x drum radius
Needed IPPT / springWaitingThe main answer
Measured spring IPPTWaitingBased on the spring dimensions above
Active length candidateWaitingNot a purchase match
Engineering boundaryThis does not prescribe spring winding. Exact selection requires the drum model and lift profile, actual door weight, cable geometry, spring material and treatment, wind, cones, shaft, track, and manufacturer or supplier IPPT/cycle tables. Geometry alone cannot certify cycle life.
Step 4
Your supplier-ready list.
Candidates are built from your evidence. I Can Handyman does not sell parts or tools.
Use any supplier you like.We do not sell parts. These are the sizes and models your photos and measurements call for; final spring matching requires supplier or qualified review.
Spring measurement record
A clean 20-coil ruler reading, optional 40-coil cross-check, and marked inside diameter.
Evidence: ruler photo + entered measurementsHigh-cycle conversion review
One wire size up and four inches longer is shown only as a comparison for supplier review.
Evidence: cycle goal + complete system geometryPhoto-matched hardware
Rollers, bottom seal, sensors, remote, or specialty shaft appear only when that project evidence calls for them.
Evidence: model label + close, readable component photosNothing here is an order.The saved and printed record is an identification aid, not a quote, purchase, diagnosis, or approval to perform high-tension work.
Step 5
Tool and evidence check.
Mark every row Have, Need, or N/A. This checks documentation readiness only; owning tools is not proof of competence.
Charged phoneEnough power for photos and a final video
Clean camera lensWipe it before identification photos
Rigid rulerReadable marks for the 20-coil measurement
Tape measureDoor width, height, and safe-distance dimensions
Bright portable lightHands-free lighting preferred
Eye protectionWear during inspection and measurement
Clear floor and openingNo people, pets, vehicles, ladders, or loose items
Manufacturer / model informationReadable label photo or typed model
High-tension boundary: Winding bars and high-tension procedures stay behind qualified review. Owning the tools is not the same as being trained on them.

Step 7
Finish with evidence.
The project stays open until all relevant checks are captured. Never stand or place an object under a moving door for a test.
Final evidence
Only perform tests permitted by the manufacturer and within your qualifications. Stop if movement is uneven, noisy, jerky, unstable, or cables appear loose.
