Who Should Choose the VIWLF128-B2?

Choose the VIWLF128-B2 when you want the flexibility of a full-motion TV mount without the bulky appearance of a conventional articulating arm when the TV is pushed back against the wall.

It is particularly useful for living rooms, media rooms, and design-focused installations where hidden cables and concealed streaming or network devices are important.

Near-Flush 0.5-Inch Recessed Profile

Because the articulating arms fold into the recessed wall box, the TV can sit approximately 0.5" from the wall when retracted.

This provides a much cleaner appearance than a typical surface-mounted full-motion bracket while still preserving substantial movement when needed.

28 Inches of Extension

The VIWLF128-B2 extends up to approximately 28" from the wall, providing greater flexibility for changing viewing positions or accessing the rear of the television.

The long extension also helps larger TVs achieve a wider usable swivel range.

Up to 67° Swivel Left and Right

The mount provides up to 67° of swivel in either direction, depending on the television's size and width.

This can help improve viewing angles from different seating positions in wider rooms.

Virtual Axis Tilt Adjustment

SANUS Virtual Axis technology provides fingertip tilt adjustment of approximately 4° upward and 10° downward.

This can help fine-tune viewing angles and reduce reflections from windows or room lighting.

Built-In 20-Inch AV Storage

The recessed enclosure can double as concealed storage for compatible streaming devices, network switches, and other compact AV components.

Six attachment locations with included hook-and-loop fastening help secure devices inside the enclosure.

Power and Cable Management

The enclosure includes knockouts for adding power and routing AV cabling. The electrical outlet itself is not included.

Any in-wall electrical installation should comply with applicable electrical and building codes.

Wide VESA Compatibility

The VIWLF128-B2 supports common mounting patterns from 100 × 100 mm through 600 × 400 mm.

Screen size alone does not guarantee compatibility. Always confirm the exact TV weight, VESA pattern, and rear mounting configuration before ordering.

Supports TVs Up to 135 Pounds

SANUS rates the VIWLF128-B2 for televisions weighing up to 135 lb (61.2 kg), including accessories attached directly to the television.

Do not exceed the manufacturer's stated weight capacity.

Requires 16-Inch On-Center Wood Studs

The recessed enclosure is designed to fit between two wood studs spaced 16" on center.

SANUS specifically states that the mount should not be installed into drywall alone. Confirm the wall construction before ordering because this in-wall design has more specific installation requirements than a conventional surface-mounted TV bracket.

Professional In-Wall Installation

SANUS recommends that installation involving in-wall technology equipment be completed by a professional electrical contractor or low-voltage technician.

This is especially important when adding in-wall power, routing cables, or modifying the wall cavity.

Before Ordering

• Confirm TV size is between 42" and 85"
• Confirm total TV weight does not exceed 135 lb
• Verify VESA pattern is between 100 × 100 and 600 × 400 mm
• Confirm two suitable wood studs spaced 16" on center
• Verify the wall cavity is clear for the recessed enclosure
• Plan in-wall power and AV cabling before installation
