Hello everybody. New guy on this site so forgive me if Im not up to speed. I have a question about a safe that was offered to me If I can remove it from where it is. It is a Schwab safe dimensions are 30" deep 48" wide 70" tall double doors. It is open and I have the combination. It is in the basement of a building. It would need to go up 5 steps. The access is limited. I measured it and the only way out is on its side due to limited headroom. My question to you is:

Approx how much does this weigh?
Can the doors be removed easily?
will the caster rollers come off?
What is the best technique to lay it on its side?

Thank you for any help with this.

Billy
