A large gasket showed around the edge, and a big wheeled lock held the door shut.

There was a creaking and straining of wood; but the lock held.

"How long do you think those locks can hold you?"

The door shuddered, seemed for a moment to bow at the centre, but the two locks held.

The container's ribbed sides looked fine, die lock was still holding.

The door swung open on its own, when the lock was no longer holding it.
