This is a tremendous bit of kit, extremely strongly made and with universal fittings for modern TVs (with VESA screw-fittings on the back of the TV). Various sizes of bolts are enclosed for different weight TVs, plus wall-bolts and masonry plugs, allen key etc. As well as movement of the elbow arm the TV-attachment has both twist and tilt functions. The whole thing is so well made and such good value that I've now bought another one for the second TV. Steve
