Top fin 125 stand

Does anyone happen to know the maximum weight this stand can hold? I got it last year for black Friday sale and so far it's been good. I've got 100 pounds of pfs right now and was gonna add 1 more 50lb bag when we move the tank. Don't wanna over do it.

The door to access below the tank has always been very tight to get open. Not sure if it was just installed a little low or what, but I haven't had any issue other than that so far.

I think I'm probably worrying over nothing, but this size tank just makes me nervous all the time.

Petsmart referred me to the manual which I don't have, which is why I asked them in the first place lol.
