Inquiry (采购产品): Ballymore Safety Seal 7980 I'd like to request any information available, esp. an owner's manual, on the above rolling ladder. It had one wheel in the front center that locked and two in the rear. Specifically, I'm looking for the designed/approved use for this type of ladder. Thanks. **** Hidden Message ***** Ric Schumann 313 Chapanoke Road Suite 10 Raleigh, NC 27603 USA Company: NC Dept of Labor Title: Health Compliance Officer Phone: 919.662.4711 Fax: 919.662.4709 E-mail: rschumann@mail.dol.state.nc.us **** Hidden Message ***** rschumann@mail.dol.state.nc.us
