The purpose of the Sinker Bar Roller Tandem Sub is to allow tool strings that are used in highly deviated well bores to be deployed easier. This sub keeps the heavy weight 79mm sinker bars from dragging on the casing creating large amounts of friction.
The sub is installed between two 79mm sinker bars lifting the string off the casing. Normally this is run in conjunction with a roller system in the Gun and Plug string. There are also Roller Sub systems available for the top and bottom of the sinker bar string.
