As you can see, there are the above 3 ways for tetherspout work with cage.
#Tetherspout Hook: From the perspective of design aesthetics, I would recommend tetherspout hook, it is removeable, once you don't need to use tetherspout, you can remove it, the cage is still on its original status. And it allow tetherspout to find a suitable angle to rest in your penis.But its flaw is the hook has a little shaking as someone said,and also would affect urinary flow as you can imagine.
#Tetherspout Locking Ring: its design concept is pretty simple as the tetherspout set sold on website has a locking ring as well. So just weld the locking ring on the tip of cage,done. This way's advantage is allow urinary flow complete and sturdy without shaking once tighten the screw.But its flaw is it would allow tetherspout tube has only one angle to stay in penis.So if the ring's angle doesn't weld with right angle, it would be of bad feeling maybe especially for the long and curved cage.
#Tetherspout Screw-on-Tip: Its design concept is also simple as originally the tetherspout was locked by a padlock. Because tetherspout tube has interconnected pores on both sides to allow rope traction and padlock locking.So weld a screw nut on the tip of cage,just replace padlock locking with screw locking. Its advantage is allow therspout find a suitable angle to stay in penis and quite sturdy
If you ignore the screw size and doesn‘t fully fill the rope hole and it shouldn't either.But its flaw is absolutely separate the urine flow into two halves, upper and lower as you can imagine.
