You are buying 1 (ONE) NEW 1" DIAMETER - 1/2" RADIUS by a Nominal 36" Long HALF ROUND ROD of CLEAR EXTRUDED ACRYLIC. (Actual dimensions are One inch outside Diameter, Half inch Radius by 35 7/8" inch long) When the rod length is cut the saw blade is 1/8" THICK. THEREFORE 1/8" OF MATERIAL IS LOST DURING THE CUTTING PROCESS. Therefore the rod is 35 7/8" long. To assure that you get the finest quality, the protective sleeve is kept in place on the rod while being cut to protect the acrylic. All rods have saw cut edges on both ends. Saw cutting can cause micro chips on the ends of the rod as seen in the pictures. Please allow a length tolerance of +/- 1/16" on all pieces.
