The belt pulling force generator is used in combination with PeniMasterPRO basic as belt expander system.

The bilateral length adjustment by means of tri-glide buckles, as well as the top-mounted multi-position anchors allow for wearing PeniMasterPRO as shoulder belt, hip belt, or knee belt. The tissue belt of the pulling force generator is very durable, heavy duty, and can be washed comfortably in the washing machine.

PeniMaster® is a professional physiologic tissue expander that can be used to softly stretch the penis for several hours a day. This passive training can increase the capacity of the cavernous bodies and, thus, the sexual stamina and stimulate the formation of new cell tissue in the penis. On the basis of the aforementioned, the penis will become longer, thicker, and straighter permanently, mostly in limp and erected condition. In the event of short-term usage, the penis will be stretched to its maximum natural length temporarily - advantageous, e.g. before having a sauna.
