Antique Safes/weight of old mosler patent safe


I have an old mosler patent safe with the following dimensions:  31” wide, 37” tall, and 27” deep, with wheels.     

Can you folks give me an estimate of the weight of the safe?  The interior is just wood shelving…   The reason I am asking is that we are considering moving it to a new location, but it has to be moved down a flight of about 45 stairs in an old commercial building.  My father moved it here  when we changed offices 30 years ago, but as he has passed, I’m not sure what the weight was. My movers would like to know so they can determine if they can move it for us…

The number on the handle is `138299’

Thanks, bob


Unfortunately Mosler went out of business in 2001, so contacting them to find out any actual information is going to be rather difficult.   Based on the serial number you have provided, the safe would have been manufactured around 1899-1901, so it would be an antique safe.

Weight is going to be in the 800-1200 lb range, probably around 1000 lbs.

Note:   With the door open to a 90 degree angle, it can be lifted off of the hinges.   This would remove about 1/4 of the weight of the safe (200-250 lbs), which would make the safe a little easier to work with.

As the hinges may be rusted, special equipment may be necessary to remove the door.   Clean, service and lubricate the hinges, with a good bearing grease, before re-hanging the door.

Caution:   Care should be taken as the stairs will NOT be in the same condition that they were in 30 years ago.   Also as this "IS" an antique safe, there are no replacement parts available, AND any damage can affect its value - dramatically!

Moving heavy items like this, especially down stairs requires special equipment and training.   Always remember that Gravity is MORE than happy to lend a hand - but it is not your friend!   You only have one chance to do this correctly AND safely.   Once you have started, you are pretty much in it until you and the safe reach the bottom - good or bad!
When gravity and weight are involved, things happen really quickly, and usually NOT for the best.

I recommend that you use a qualified safe moving or rigging company that specializes in moving items like this.  It may cost a little more, but its better than experiencing a loss of life or limb!

Hope that this helps,
