A dual tension racket string tensioning system and methods for implementing the same are disclosed. Embodiments of the disclosure include a tensioner equipped with two or more receptacles to releasably grip two or more portions of string simultaneously, and simultaneously apply a force at each portion of the string held in the receptacles. Embodiments of the present disclosure include a turntable rotatably coupled to a base structure, a mounting support adjustably coupled to the turntable (the mounting support configured to receive and hold a racket), and a dual tensioner, as disclosed herein, coupled with the base and operable to apply force (1) at a first portion of the string via the first receptacle; and (2) at a second portion of the string via the second receptacle. Some embodiments further include a stationary dual-string clamp. Further embodiments include a gear dial for fine tuning the force applied to the string portions. And still further embodiments employ a frequency meter to measure the frequency/pitch/tension of individual string segments throughout the stringing process.
