A client wants to mount a tv on a swinging bracket that slides out from one side of a box. For the mock-up I used a pair of Richelieu 100 lb full extension slides mounted one above the other, The mocked up tv panel twists when extended due to the slide construction. I am considering a pair of Accuride 9301's. I have used them before, but not in this configuration. Any opinions on their suitability or alternate suggestions?
