How do you prevent strut damage when car is put on the lift.

What is your question?

Dealership has said (friend that is a single Widow) that by putting the car on the lift for a brake job, that the struts extend fully and can cause damage. And that they are not responsible for any such damage. Is there any "jigs" or other such tricks of the trade to get around this damage risk? Thanks in advance for the assistance.
