I found this to be the ripper setup I was after. Strong and sturdy, you will be able to add, which I'm going to down the track. Strongly recommend the item.., The item was well wrapped.
Very well made and easy to use. Gliding surfaces are very smooth and operate with little effort. Since the slides are bearing mounted it help reduce router noise from vibration.
They are very high quality, I just wish they came with the screws that fit into the threaded holes or at least list the thread size to make it easier to find the screws.
