How long are replacements grommets sold after a racquet is discontinued?

[NickH87]

Simple questions because I bought 2 used racquets and was thinking about buying some new grommets because I am replaceing everything anyway but I forgot to order them with the other stuff and was going to wait until the next string job....any clue to how long they are sold?

I think for quite a while. TW has a huge selection on grommets for new and old rackets
