How tight should a garage door opener chain be?
The chain should be tightened until it sits, at its midpoint, about a quarter-inch above the rail for a square rail and a half-inch above the rail for a T-rail. It’s important that you don’t over-tighten it, as this will cause the chain rollers to wear out prematurely.
