The EziPlate single is easy to install into most caravans with a wall thickness up to 35mm. The unit is fitted by drilling a 10mm hole through the van wall and pushing the connector through from the inside until the wallplate is flush. Then, simply fit the external waterproof rubber washer, stainless washer and nut. These external fittings are weatherproofed with an included silicon cap to keep out dirt and rain. Installed in minutes with a no loss connection. Screw on F type connections that won't come off or work loose. RG6 F connections are standard for use with satellite TV and will become standard in all vans for television antennas too. Our EziPlate threaded, adjustable connector will fit van wall thicknesses from 15mm up to 35mm without the need for any extensions.
