Jerry:
I bought 2 rolling Al stairs with the safety rails from Granger.
They are a bit overkill. A student had a misstep when she put her foot
on it and fell. She suggested removing the spring-casters. With the
casters removed they are more stable and we have had no problems. I do
not like the rails, but I do not want the liability either. The nice
thing is that while stable, they can be move away easily. Stairs=fine.
Cheers, Lew
