All the PAW International mounts I found at:
The black Wall bracket has a hole pattern of 100mm X 100mm (4" X 4") which is the VESA standard for a 30" or smaller TV. If you have a swing arm it likely has this same hole pattern. Rather than go from wall to bracket to swing arm to TV, I went from wall to swing arm to wall bracket to TV. Now I have a TV that is removable that slides into swing arm. Best of both worlds. PAW makes several other cool products that are available on their Ebay store that I haven't seen anywhere else. I carry a small pump that is powered by a 2 cycle motor. I carry a small gas can in my RV but I can never remember if I mixed the oil in with the gas or when I need to mix the oil what the mix is for the pump. Coolest thing they carry that takes care of all my issues. I bought them for the whole family for birthdays and Christmas. Gifts, CHECK!
