The PINPOINT MOUNTS PPM-EX Extension adapter plate can be used with most brands of PLASMA/LCD mounts that have vertical mount arms extending the horizontal mounting width up to 9" more. This extension converts the width of a mount to accept a larger mounting pattern such as the VESA mis-f 800,400,8 pattern found on some NEC, LG and Philip's TVs. The PPM-EX is steel construction and is in a metallic silver finish Pattern. This is a cost effective way to convert your older mount to accept a larger pattern. Note: the PPM-EX may not work with every mount. If you have any questions please contact customer service before ordering.
