On the Sanus site it does not have the VMPL50A-B1 listed as a compatible mount for the 65gt50.
Im not sure why... as the box says it fits most up to 70"...AND if you look up the 60GT50 and the ones smaller down the list on the GT50 sizes, it does have
the VMPL50A listed as compatible.
What is odd is that according to Sanus... if you look up the VMPL50A-B1... there is NO SUCH THING as a B1.
Not even on their discontinued list. I find this odd because I just bought the same model as you... with a B1 at the end.
I am curious as to why this is... and if they have a few VMPL50A models that end in something else.. and they mean the whole series of that
number will fit.
I hope this is true because I live in a small town, this is the only model mount in ANY brand at a store here that is close to seeming it claims to
work with my new 60GT50... AND if it doesnt it means I will have to order a different one online and have to reschedule the installation of my new TV
which the installer says would not be for two weeks from now!
