conversion plate kit: This mount conversion adapter plate for TV and screen mounts allows you to convert from one pattern to another to connect mounts and that are otherwise incompatible. Converts common patterns and sizes: The mount adapter can convert to the following pattern sizes: 50 x 50 mm, 75 x 75 mm, 100 x 100 mm, and 200 x 200 mm. Connect devices: If your mount, stand, or arm does not have the correct hole patterns to match your device, this adapter plate will allow you to mount it by converting to the standard sizes. For example, you can mount a 200 x 200 mm monitor to a 100 x 100 mm stand with this adapter plate. Please note; the Adapter Plate will extend the mount's reach but it WILL NOT expend its weight capacity. Make sure your mount can handle your TV's weight.
