I've recently got a new TV and I was hoping to use the old bracket, but I've lost the plates to extend the 200mm x 200mm plate to 300mm x 200mm. I've got a length of this:
If I secured the bar to the bracket plate with 2 bolts, and fixed to the TV with 1 bolt at each of the 4 points, would that do the job? The new TV's about
15kg, and the bracket is rated to 40kg.
