Adjusting the tension of a Jes extender

Hello one and all. :)

I have recently started using a Jes extender again after a long break, and I’m hoping that some of the members here might be able to help me with a question that I have.

The Jes extender comes with three tension markers on the bars - one at 900g, one at 1200g and one at 1500g. At the start of a session I set the tension to between the first and second markers (I.e. Between 900 - 1200g). However, when I check the device after ten minutes or so, I usually find that it has now slipped outside the area of the markers slightly, to below 900g. If I check again after half an hour, it will often have slipped even further.

My question is this - should I adjust the tension throughout the session to keep it between the markers, or do I just set it at the start of the session and then leave it? My sessions usually last an hour, then I take it off to get the circulation moving again and apply some heat.

Many thanks to you all for your help!

I adjust the tension during.

That’s what I do to. As long as you’re not overdoing it, there’s probably no harm in adding an extra bit of tension during a session.

Adjusting the tension to a level you want it to be when your penis has soften and become more flexible, is the thing to do. When the adjusting screws are too far out ( they start to unscrew themselves on their threads), and you are not able to get the desired tension without unscrewing the screws, you will have to put in some new rods to extend the extender, and start with the adjustment screws at starting point. For a Jes extender, they usually sell 1/2 inch, 1 inch and 2 inch rod parts, however, there is some vendors that sell 1/4 inch parts online, that may/may not fit or have the same threads.

Many thanks, Norwegian Wood - I’ll bear all that in mind.

I have started PE week ago after years of break. How much tension should I use? Is it detrimental to use almost full tension right away after first week? Or do you ever need 1500g if hours are 10h+ per day? I use between 2 and 3rd marker. So like 1350 - 1450g per bar (total 2700 - 2900g).

I start with 900g and after 10-15min I go to 1350-1450 and I have to adjust many times more tension so it stays there. I think that it good sign when you have to adjust, because some stretching has occured.

I want to avoid unnecessary tissue toughening that occurs when too much tension is used too fast.

Trapezius; you should start as a beginner, in the way that the Jes manual instructs. Start easy with the lowest tension, since your penis needs to recondition itself to the workload ahead. If you have an original Jes, ( atleast a model that is some years old), the springs are delivering tension of 600/900/1200/1500 per pair - not each side ( each rod). If your extender have harder springs, the numbers could be at the level you are mentioning.

I have Jes Titanium.
Springs have 3 markings and I measured them with kitchen scale and they are 600/1200/1500 grams per spring. Measured again both springs at same time and they produce total 1200/2400 and 3000g of force.

I will do about 2000-2400g total tension for few months and see if that produces any gains. It should be enough tension when enough hours are put in.
