No and it's all "keystone" jacks inserts not just the 8 pin.
There is no standard so manufacturers do what they want, probably so you will have to buy everything from them. Some will fit in another manufacturers plate but I find that most will not. Most times you wind up changing everything just to add a jack.
I think your chances are better if you stick with one of the major players than a no-name bargan brand since most conscientious installers are going to provide one of the major brands.
