1/4" x  2-3/4" top x 3-1/4" bottom  Foam Roadbed.  This auction is for 10 pieces 72" long (60'), light gray in color. This roadbed is a very dense foam, much firmer than the Woodland Scenics foam, and has great sound deadning qualities, It can be curved without sliting, easily cut with a sharp knife, and will not harden with age. A great substitute for Homasote or cork. This same material is available in black, look for it in my other items. I accept only Paypal and ship USPS. I can custom cut widths in this material for different scales or yard mats. Please ask questions before you buy..I will send you a sample, just email me with your name and address thru the ask a question option.
