The correct spring specification depends on the door system, not a one-size-fits-all replacement.
The whole door comes first
Spring selection calls for an assessment of the door’s characteristics and the installed system. Changes to panels or other components can affect what is appropriate. A technician should establish the relevant specifications rather than choosing a spring because it resembles the old one.
Useful information you can share
Have the door’s manufacturer and model available if known, along with photos that can be taken safely. Explain previous work and any recent changes. Do not remove a spring or handle tensioned hardware to obtain measurements for a phone enquiry.
Ask about the completed repair
Request a description of the parts supplied, related hardware concerns, and the checks performed after installation. Keep the service paperwork for future reference. If the door is stuck or a spring appears broken, leave it alone and contact Bonita to discuss service availability in your community.
