Help Finding Extension Cord, 250v, 50amp outlet?

Hello,

I'm trying to shop around for a possible extension cord for this 250v, 50amp outlet.

We'd be trying to use an electric dryer from this, but would preferably have it extend nearer a window on the other side of a garage (~25-30 ft, generous measurement). We'd likely pick up an older, used, basic dryer model, and not sure what those electrical needs will specifically be, but trying to plan ahead in case something needs to be altered.

This is the closest I've found which might work:

Most other cords with 3 prongs had them sort of curved/circular. Yet, this says only 30 amps.

Is there different or specific wording which might assist my search? Or would something like the above cord work for our situation?

Thank you for taking the time to read my post. I appreciate any advice or directions.
