The VisionMount HDpro™ Series XF228 was engineered with the custom installer in mind. Its pre-assembled interface and strong, ultra-light extruded aluminum wall plate allows the easiest and quickest installation possible. The QuickConnect™ system allows the mounting head to snap onto the arm assembly with one easy movement and unlock with the push of a button. ProSet™ post-installation height and leveling adjustments ensure TVs are always perfectly positioned after mounting. The XF228 arm assembly shifts left and right on the wall plate so the TV is always centered, even if wall studs are not. And the amazing FollowThru™ in-arm cable channel protects and completely conceals all cables without inhibiting movement, even through the elbow. Strong dual arms allow even the largest TVs to extend, retract, tilt and swivel up to 28" from wall with ease. Virtual Axis™ tilting technology allows effortless viewing angle adjustment with the touch of a finger. Universal mounting pattern fits virtually any 42" – 63" flat-panel TV up to 200 lbs.
