Good quality, more professional way to run cables through on boat. Wish they made slightly a bigger size flange to cover previous hole made antenna but was still able to make it work. Only way to run cables in my opinion from now on. I am a professional recreational boater that likes quality and everything to look professional and nice.This is exactly what I needed. However I found it cheaper at the marine store in town.Just added a chart plotter, fish finder, depth sounder and marine radio to my boat. These outlets were a perfect waterproof solution for topside cable holes.I really like the design. Chrome over brass too. The quality is very good.Multiple grommets are included so it was easy to install. Would be nice if it included some SS screws as you must supply your own fasteners.This little gadget provides a neat and clean seal for where the antenna line goes through the hull. Installation is quick and easy. Just select the washer that matches the size of your cable, feed the cable through and snug up the nut.It does what it is supposed to do---provide an outlet for a cable on our boat. It's still in one piece and seems to be sturdy enough. No complaints on this purchase.Nice part
