As standard the Seimitsu LS-32 main guide installed behind the adjustable sub-guide is a square type.
With the alternative square guide you will have a similar operation to the Sanwa GTX-R Type I square guide.
This alternative square main guide provides a smooth circular entry while featuring pronounced grooves for all four directions.
This main guide replaces the light blue square guide on the Seimitsu LS-32 and LS-32-01 joysticks and fits under the dark blue sub-guide.
