# Spring cycle rating

A term used when buying garage door.

The number of open-and-close cycles a torsion spring is built to survive before it breaks.

Springs are the [recurring revenue](https://searchspheresource.com/glossary/mrr) under a service book and the reason that book is worth more than an install book. A standard spring is rated for a fixed number of cycles, commonly quoted around ten thousand. That is a few years for a household opening the door several times a day and much less for a busy one, so every door in the territory is on a clock whether anybody is tracking it or not. Ask what share of service calls are spring replacements, and whether the shop stocks the higher-cycle spring, because selling that upgrade is a margin decision made at the customer's curb.
