The SANUS HDpro™ Series LF228 full-motion mount for 37" - 65" flat-panel TVs up to 135 lbs / 61.36 kg. 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 LF228 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. Its strong extension arm allows large TVs to extend, retract, tilt and swivel up to 28" / 71.12 cm from wall with ease. Virtual Axis™ tilting technology allows effortless viewing angle adjustment with the touch of a finger. Universal mounting brackets. Mount now fits TVs 37” - 65”, and all current LF228 models have been tested for compatibility with the updated size range.
