Query: Cannon swivel base

It does the job it is supposed to. Stainless steel screws are included for its mounting so it makes the job of installing easier. There was no searching for the correct screws to use and everything fit. To use just pull the 'T' handle and it pivots around and has locking positions where needed. I swing my downriggers out 90 degrees from the boat then when going to and from the fishing grounds swing them aft and out of the way which is why I bought this great non-rusting product that I use on a 19 foot ocean going boat. Thanks Cannon.
