    The tapered rod strings are designated by 1/8-in. (in diameter) increments. Tapered rod strings can be identified by their numbers, such as: 1. No. 88 is a non-tapered 8 8 - or 1-in. diameter rod string. 2. No. 76 is a tapered string with ⅞-in. diameter rod at the top, then a 6 8 -in. diameter rod at the bottom. 3.
