The plastic masts provided with the spreader kits won’t last more than a season Even within that first season whatever you mount on the plastic mast such as a GPS receiver or weather station will be bouncing all over. The stainless threaded mount isn’t available anywhere else and is the perfect solution for adding fiberglass/ss ferule mast extensions. The resulting assembly will keep your devices rigidly mounted and withstand all weather extremes. SeaView makes an excellent product
