			Dear  Mr. Reynolds:
			In your letter of April 10, 2009, you requested the Federal  Highway Administration (FHWA) acceptance of the WZ Deluxe Tri-Pod temporary  sign stand as a crashworthy traffic control device for use in work zones on the  National Highway System (NHS). You  requested acceptance of the temporary sign stand for use with the following  sign substrate material: 1/2 inch thick plywood, 0.125 inch thick aluminum, 2  mm and 3 mm aluminum laminate, corrugated plastic, and roll-up material. Your request for acceptance is based on the performance  of the generic tri-pod sign stand accepted in FHWA letters WZ-240 and a similar  tri-pod stand in WZ-207. Accompanying  your letter were the FHWA Office of Safety Design forms that included a drawing  and a detailed description of the WZ Deluxe Tri-Pod. Drawings of the WZ Deluxe Tri-Pod are  enclosed for reference. You requested  that we find the WZ Deluxe Tri-Pod acceptable for use as a Test Level 3 device  on the NHS under the provisions of the National Cooperative Highway Research  Program Report 350 "Recommended Procedures for the Safety Performance  Evaluation of Highway Features”.
			This letter  acknowledges FHWA's acceptance of your request.  The original completed forms have been modified by the addition of the  FHWA acceptance letter number and the date of our review. The forms will be posted on our Web site in  the near future.
			Sincerely yours,
						Signature of George E. Rice, Jr
