OSHA & capacity markings

[sands]

Hi everyone
Newbie has a question. I have shelving that has been identified by OSHA as lacking capacity marking. I don't believe this to be the case because each front "rail" or box beam has a stenciled marking "1880/PR uniform load". Problem is I have no idea what that means? And I can not find any other identifying markings, purchase order etc. for these racks. Any help would be appreciated.
Thanks

If nobody knows what it means, I'd say so too.

Anyway, maybe these guys can tell you.
