For those using PeniMaster Pro or Vac Extender 3/4

[Craig]

I'm trying to order the Vac Extender 4 attachment to use on my PeniMaster Pro. For the Vac Extender order page, do I pick 8mm or 9mm rods (for it to be compatible with the PeniMaster Pro)?

And does anyone know what "Cylinder Size" refers to on the order page? Is this the inner or outer diameter of the glans chamber of the Vac Extender?

Tonight I tried my final attempt in getting my glans into the PeniMaster Pro glans chamber, but the chamber is just too small (or the large sluice and large adhesion diaphragm are too narrow).

Craig,

I am not familiar with the PeniMaster Pro but regarding the extension rods, you need to carefully measure the diameter of the extension rods on the PeniMaster and determine if it is 8 or 9 mm wide.

If the rods are 9mm and you order the 8mm Vac Extender, the rods will not fit into the device. The reverse should be OK, if the rods are 8mm and you order the 9mm Vac Extender, they will still fit into the device.

Just a reminder, if your caliper is in inch only, 8mm/25.4= 0.315"; 9mm/25.4=0.353"

Thanks guys, but I was hoping someone with the PeniMaster Pro could give me the exact diameter of the rods so I don't have to buy calipers and do it myself. Where can I buy these calipers? And which part of the rod expander do I measure? The outer diameter, or inner screw hole diameter? If you google images of the PeniMaster Pro rod expander, you see there's a couple different widths.

Also, for the donut looking thing you stick your penis through to get it on (on all traction devices) that goes against your body while you're wearing it, is it normal to have to use lube to get this on and off, and have it compress the base of your penis inward (like temporarily reduce the girth) while you're wearing it? I'm afraid its too skinny as well and don't want to damage my penis any further.

Really disappointed with the PeniMaster Pro in general.

Craig,

I measured the diameter of the rods using a plastic ruler I had in our house and a magnifying glass since my eyesight is not that clear anymore. You need to measure the outside diameter of the rods. I didn't even consider the measurement of the screw hole diameter and fortunately it fit.

Many rulers are calibrates in inches and millimeters. The plastic ruler was semi-clear so I could hold the rods against it and look through the ruler from the other side to measure the diameter.

Thanks for the help. A clear plastic ruler is a great idea and would probably be easier than learning how to use a caliper (or what a caliper is for that matter).

Unfortunately I think I'm going to have to cut my losses on the PeniMaster Pro as the donut hole on the rod expander system is too skinny for me to get my penis through with out risking further hour glassing or injury. Does anyone know of a traction device that will accommodate above average girth? I'm 6-7 inches in girth and just need to find a rod expander traction device system that will let me get my penis through it, and I'll order the largest size VacExtender glans chamber to attach to it.
