Hello all, I have an superceded Ryobi router model. I need a 12.7mm nut and collet for it which according to Ryobi no longer carries for an ERT2100VK. In any case I prefer to buy an aftermarket one but there isn't one I can find that states as being compatible to Ryobi. I've done a heck of allot of browsing, only useful but of info I've found is that somebody has been able to fit these parts from a Makita. The point being, Makita router nuts aren't the same across the range. I'd appreciate if anyone is able to help me please with identifying compatible models. Thanks
