Needed a cost effective and top end solution for NL8.
Neutrik NL8 plug is made from a hard plastic and features a metal clip for locking in the socket.
They can be a slight fiddle to wire in the 8 cables, but once you have done a couple it becomes very easy. You'll need a good quality screwdriver and some patients!
Once wired, it makes a very solid plug. The cable grip must be used to prevent cables from coming out of the plug.
All in all, top notch.
