The PeniMaster PRO rod penis expander system in sectional view

The rod system of PeniMaster®PRO for adaptation to the penis length

Note: The base support is also suitable for PeniMaster.

The device can be applied to penis lengths over five centimetres (measured in the stretched condition of the penis). Even in this smallest expansion stage, the spring balance for pulling force control is fully functional with two centimetres range of spring. The device can be adjusted precisely to all penis lengths. This is allowed for by differently long, inter-combinable extension rods (Fig. 1 and Fig. 2). 
The scope of delivery covers extension rods for penis lengths of up to 30 centimetres. The length of the device can be extended as required due to further additional rods. If the delivered extension rods are no longer sufficient, each rod pair can be re-ordered at a later point in time.

Extension rods

Rod pairs in stages of two centimetres each can be screwed to the base rods fixedly assembled with the base ring and can be inter-combined (Fig. 2). For fine adjustment purposes, three rod pairs with 0.5 centimetres screw-on length in each case are delivered.

[!] Note: The base ring and the extension rods are suitable for PeniMaster and PeniMaster PRO. The holding support of PeniMaster is mounted in this figure.
By combining the different sets of extension rods and taking advantage of their individual lengths, the right setting for each penis is easily found. The featured devices were extended step by step by two centimetres each time. Between each of the featured steps, even smaller individual steps are possible by utilising the 0.2" / 0.5cm extension rods. This will give you the possibility to get up to 30 more incremental steps (not pictured above).
