    When installing grommets, it can be really difficult to insert flared grommets into the holes on the frame, and 10x worse when try to push the grommet out of the hole if you know what I mean. Often times I end up damaging the grommet, and those flared ones are usually where you tie the knot which puts more wear and tear. Is there an easy/graceful way?

    Buy new grommets or heat the used grommets gently and mold them back into shape.

    Thread by @petercoffey. Reshaping flared grommets before trying to reuse is what you must do. Other choice is to cut that tube off and use a FITTEX replacement tube of the same size. Cut to length. Personally, I would go with FITTEX since tie off hole grommets are normally pretty much destroyed.

    Thanks for the comments guys. The problem is the grommets I was using were new - I needed to add some lead at 12 on a Yonex DR 98 under the bumper guard, and the new grommets had quite pronounced flare. I really struggled. On other frames, new grommets that I have used usually dont have such problem. I'll see if I can upload a picture later on.

    PS - I assume this is the thread referred. https://tt.tennis-warehouse.com/index.php?threads/help-for-tired-grommets.370677/ Marked and will read carefully.

    I’m assuming they were new when you installed them. Then I’m guessing you strung the racket. After that you flared the grommets and they are no longer new.

    Actually, when the racquet was brand new, never strung once, I removed bumper guard, put on lead, tried to put it back. That's when I had problems with the flared grommets.

    What racket? Some manufacturers flare the grommets that are prone to backing out when you pull tension, and those used at tie off locations. If you’re going to take them out I suggest you buy new (not flared ) grommets.

    It was the Yonex DR 98. Are you saying they may offer 2 versions of grommets (one flared like normal stock version, one non flared)?

    My guess is that those tie-off holes were flared from manufacturer. The best scenario would have been to lift it off the racquet just a bit, only as much as the flared grommets allow and not completely out, and try to slide the lead tape in under the bumper.

    No what I saying is Yonex flares the grommets after they are installed to prevent them from backing out when strung and to protect the grommets when tying off. If you take them out you need a new set that is not flared so you can install them in the racket. After they are installed if you want to flare them you’ll need a flare it tool. But after they are flared do not take them out unless you want to buy a new set or straighten them back out.

    EDIT: On the DR 98 grommets 7, 9, and 11 Head are flared.

    THIS is where you went wrong.
    You removed the bumperguard (that originally came with the racquet) with the intention of trying to put that same bumper guard (with it's flared grommets) right back into the frame.
    Bad move.

    Your first post made it sound as if you were installing a replacement grommet set (which, to my knowledge, would never have flared grommets).
    When I read your first post, I was already pondering to myself "where did he get a replacement grommet set that ALREADY has flared grommets".
    Then, as I read the subsequent posts, it became clear that you were not installing new grommets, but trying to RE-install the factory grommets, that you removed.
    Unfortunately, you've learned this particular lesson the hard way.

    Ahh... now that makes perfect sense. Thank you! Never knew they would flare the grommets AFTER factory installation.

    Well, I learned something new.

    But on the other hand, I'd argue this is not a great design. They flared the grommets after installation as a solution to fix an issue due to a less-than-ideal design and prevent it from backing out when strung. Not very DIY friendly.

    I could try that too.

    The manufacturer's flaring job is good for those grommets because it prevents them from getting torn by tie-off strings or extremely-angled strings.

    I have a few new grommet sets for the blue if you are in the market

    I may have led you astray with my reply. Grommet holes 7H, 9H, and 11 H are all flared but the only main that tends to pull out on the top of the frame is 9H when you tension the 8th main. Grommet holes 6H and 7H are the normal tie off holes for that racket. (I’m not sure if 6H is flared or not.) Yonex flares the tie off holes in the bumper so the knot used to tie off does not chew up the grommet. Actually it is a good idea and not a bad design.

    Then there is grommet 11H. Both the mains and the top cross ties off at the head of the racket, but some people like to tie mains on mains (tie off mains at 7H) and the top cross on a cross. If you want to tie off the top cross on a cross use a starting clamp and tie off at 11H (3rd cross) after stringing the fourth cross. Hope that makes sense.

    You probably need to buy a new set of grommets. They will not be flared. If you want them flared, there is a tool called "Flare-it" (if they are still made). They work great.

    The flare it tool has been discontinued a few years back
    I let someone borrow mine a number years ago and never got it back, and now no longer sold.

    See post #3. I would rather use FITTEX grommets rather than buy a new grommet set. That's if OP cannot unflare the old flared grommet. As for flaring the tube, you don't really care since the FITTEX tubes can be replaced whenever needed. But if you insist, the DIY C-clamp method works, but so does the pointed pencil/wooden dowel.
