Inquiry (采购产品): Need HDS-10 info We are interested in the HDS-10 Stairway Slope Ladder, but I need to know the tubing diameter and the center-to-center distance between the upright supports on the tall end. Is there a different part number for the rear exit version? **** Hidden Message ***** Peter Brusati 862 East Hospitality Lane San Bernardino, CA 92408 USA Company: Northrop Grumman Title: Mechanical Engineer Phone: 909.382.6689 E-mail: peter.brusati@ngc.com **** Hidden Message ***** peter.brusati@ngc.com
