3S-HD-PTP-6  Heavy Duty HDG Pole to Pole Mast Mount 1.25" to 4.25" OD 

Heavy duty pole to pole mast mount. Attaches two pieces of tubing, antenna mast or pipe together. Both clamps are the same size and can clamp onto an outside diameter between 1.25" OD to 4.25" OD. The pipes can be of different diameters just as long as they are within that range. (For example you can attach a 1.25" OD antenna mast to a 4.25" OD mast.). These pole to pole mounts are perfect for attaching a smaller diameter extension pole to a larger base pole to get that extra height. The mounts are alligator style, which allows them to attach firmly to almost any kind of wood, metal, fiberglass or plastic pole. They are Hot Dipped Galvanized  ( HDG ) for superior weather protection making them great for outdoor use where weather conditions are wet.
