    Prince O Port rackets allow the racket to play to the edge. That is to say the string pivots on the outside edge of the frame instead of through a grommet then pivoting on the inside of the frame. Because the string pivots on the edge of the frame it rubs and the frame itself and wears a grove in the frame. isner had a problem with his string breaking so he has tubing placed on all the ports to protect the string. The strings in this racket did not break because of the wear this time but it will not be long if the strings are not tubed. You can see the wear in the picture below:

    Here is the finished product. I try to cut the tubing long enough to protect but not go past the inside of the frame (about 1".) on the 6th grommet hole I use about 1/2" so I can protect the frame but not block the normal grommet for the top cross.

    I don't have a Prince but I thought the O-Port was a type of replaceable grommet. Am I wrong Irvin?

    The O port is a big hole with no grommet. Thre are some vibration dampeners in the bottom of some rackets and some frame that have pin hole grommets but for the most part it is a big empty hole as in the pictures.

    I have a o3 emerald that I played with for 4 years in highschool. Played about 20 hours a week. Back then, sure I wasn't as good as I am now and I didn't break strings, but I never even got close to having my frame look like that. All I see is the paint that got sunk in where the string goes, but that's it.

    OH and I strung my first prince ported racket tonight...I REALLY enjoyed it, and the only part I got kinda confused on was starting the mains because this particular racket started the opposite of the other rackets I've done. It's the same pattern though...is that just the design? I'm probably gonna be a loyal prince user now.

    I have Prince Hybrid Tours with the O Ports on the side and mine don't chip like that either. I guess you need a little more muscle than we have. LOL BTW a C level (USTA 3.0 level) lady playing with that particular racket.

    Lol maybe!!! Or maybe it was stringing error or from a stiff textured poly?...anyhow, really actually enjoyed stringing a prince ported frame.

    Thanks Irvin. Tubing is a great idea. My bag has 6 O-Ports in it and I string quite a few for others. A very popular brand here in Scottsdale, Arizona.

    I can't think of a stringing error that would cause that, and the racket was strung with Prince Lightening XX. I have to admit though this racket and two other Hybrid Shanks are the worst I have seen. I think it all has to do with head size, how hard you, spin, and string vibration.

    My suggestion is if you see any paint chipping in the Ports tube them. Takes a little more time but worth the effort and won't change the playing characteristics unless you use too much tubing.

    Thanks. I've run into this problem stringing O3 Reds near the throat. Same solution, tube the area.

    I haven't tried this but will. How do you keep the tubing in place when you pull tension? It seems like pulling tension would move it.

    It does just a little but not much. I cut the tubing so it is just about 1/8" shorter than enough to reach the two insides of the port. I place the tubing on the center point and start mains with the Yusuki method. I first pull the left main for rackets that start at the top and most Prince rackets to. Before pulling tension on 1LM I place the tubing so it is at the bottom of the port on 1RM then pull tension. It sides toward the pulling for some but very little. Then do the same just about for all others.

    I also put a short piece of tubing on the outside of the throat mains which are usually the fourth mains. It is had to put tubing in the grommet holes of the prince rackets but sometimes I use leather power pads in the center three turns in the throat area.

    I know Isner puts tubing on the side O ports of his racket but I have only ever had problems with the mains. Here is a picture of Isner's racket curtesy of Drakulie. Hope he does not mind me using it:


    EDIT: You can see in Drakulie's picture the tubing pieces are quite long and extend past the frame. I don't do that because I fell it may deaden the string (but it probably won't.) with the clamp as close to the frame as possible there is very little movement of the string through the grommet hole when you pull tension so the tubing moves very little.

    EDIT: I quests when it is all said and done the amount of tubing creep will depend on the amount of drawback on the clamp and the amount of stretch on the string. You will see very quickly how far it moves when you pull tension. If it moves too much for you just reposition the tubing and pull again. You would be better off pulling the string though as little as possible so make sure your clamps are as close to the frame as possible. I would prefer to allow the string to protrude a little than repulling.

    Thanks Irvin. I book marked you reply so I can reference it later. I string for 2 guys that play with these. Will give it a try..

    P.S. - Think I'll practice with some old string on the first attempt..

    I had two more of these Prince Hybrid Sharks come in today. One in good shape and the other not so good.

    [​IMG]

    If you look at the right side of the two left ports you can see where the string was eating away at the frame. On these frames I put tubing in the top of both frames in addition to tubing and power pads on the bottom. Only one needed it but I figured they would feel different if I only did one.

    the o3/oport rackets that can use stringhole grommets won't see this issue, yet they still play somewhat oport like.

    Those type grommets are normally on just the sides and not the 6 and 12 positions.

    The Ektelon O3s have the same problem only more so as racquetball people tend to hit high up on the frame and the strings are much looser.
    I've not run into the problem at the throat on the Princes, though. Only between 11 & 1, and sometimes at 3 & 9.
    The squared off holes on the Speedports and EXOs solved much of this issue. Not completely, but better.
