I just received my OmniMount UCL-X today, specs are for 42-63" panel, 200lbs.

Whatever problems the old OmniMounts had, this is a totally new design and built like a tank. Construction is cast metal, the 2 arm wishbone design is well balanced and reduces torque (I wouldn't trust any single arm for a 50" panel).

OmniMount has been listening, hope all you pros will take a second look.
