    Do any of these work like the RAB ones below?


    Assuming I didn't mess up, the pic should show that this grommet protects the string. I was thinking these would be good at the 10/2 o'clock positions to protect the string from careless shuttle scooping.

    Not so good for me as a stringer, but I have at least one client who would benefit from these!

    That client should work on his/her skills. Shouldn't be using the racket to sweep the floor. o_O

    But seriously, these might be hard to use on the 1-2 and 10-11 o'clock position where I assume the most damage might occur. The grommets are quite crowded around those areas, would there be any space for these"RAB" grommets?

    Immediately I have two clients in mind who would also benefit a lot from these, although I am with mikomi when it comes to the question if there will be enough space at those areas. It has to be said that there are some rackets who provoke these shuttle sooping damages since they are exposing the string a lot.

    @emjay
    Where can those RAB grommets be ordered?

    http://www.r-a-b.com/ - unfortunately those are tennis grommets.

    I always tell people to try and change their scooping habits when I notice breaks like that but some people can't seem to stop!

    Still using stock grommets on the JS10, but I did replace the triplet grommets on the 11 and 1 oclock position with the small T-grommets.. I found that I was able to aim the grommets to guide the string so they don't overlap each other. I'll be using fresh grommets on the racket next time I string.

    I ordered the small T-Head and the L shape grommet. I was able use the L for T5 on the JS-10 (BG-80 @ 25 x 27.5 lbs).

    I also ordered the new generic grommets and have yet to try them out.

    Below are more details of the grommets.

    Question: What do you use to flare shared grommets on the inside of the frame? I had some trouble lately that especially the square-headed grommets don't open up when the string is pulled (which is what I usually do with the standard MBS grommets without any issues) but instead the string cuts right through it.

    Looks interesting. What's that tool called?

    Edit: Or is that the tip of a soldering iron that we see there?

    I was hoping for a solution that doesn't involve a soldering iron or heat in general. There once was a tool called flare-it, but it seems that it's no longer available.

    To answer your question: that is the tool I own to flare shared grommets.

    Just curious but is it me or does the plastic used for the L shape and Red shape 2.7 & 2.6 mm grommets seem stronger than the Large T-Head for shared holes?

    Darn it. That thing was brilliant - what a shame that apparently it has disappeared completely without anything similar to replace it.

    The red T-shaped are indeed extremely strong. Weakest of all seem to be the square-headed shared ones. They get cut very easily by the string on the inside of the frame. Even the standard shaped ones are opening up a lot better.

    Ok it seems there is mutual agreement to improve the strength of the squared headed shared grommet. It seems softer an thinner compared to the L, Red T-Head, Small T and the new generics.

    I only noticed this more when i tried flaring the grommet with the Flare-it tool. Grommet would split as it's flared but the others wouldn't. As a result i would have to punch out the grommet and replace it.

    Hopefully Dennis can reach out to his manufacturer to correct this in future batches. Other than that, the general consensus is that Dennis has made a tremendous contribution to the stringing community with these fantastic replacement grommets. As you can tell from my photos, i'm a big supporter! :p

    If he reply...he didn't want my money. I'm not the only one. Went for Li-Ning Grommets, now.

    I believe he mentioned on his blog post that the red bit T grommet was conceived to be better than the black big T grommet. I haven't had any issues with the black T grommet except that I have to shape the head into a curve making the grommet look like a pickaxe so that it matches the curvature of the frame better.

    You managed to get a hold of Li-Ning grommets?

    If i understand your email, I know he was away for 2-3 weeks in June. He didn't reply to me until early this month.
    I'd suggest you contact him again.

    That's truly the question of the day. Where and how did you get hold of Li-Ning grommets? Did you also get their square-headed ones? And how are they in general compared to the YY ones?
