SANUS Preferred 26"–65" Full-Motion TV Wall Mount SMF421A-B1, 21" Extension and 60 lb. Capacity

Position your television for comfortable viewing with the SANUS Preferred SMF421A-B1 Full-Motion TV Wall Mount. Designed for compatible 26"–65" TVs weighing up to 60 lb., the mount extends as far as 21" from the wall and retracts to a low-profile depth of 2.1".

Dual articulating arms provide smooth extension and swiveling, while tool-free tilt helps reduce glare or improve the viewing angle. Integrated cable-management channels route power and HDMI cables along the mount arms for a cleaner installation.

Full-Motion Adjustment

The dual-arm design allows the mounted television to extend, swivel and tilt for different seating arrangements.

Available adjustments include:

• Extension: Up to 21"

• Swivel: Up to 90° left or right

• Tilt: +4° upward to -15° downward

• Leveling: Up to 6° after installation

• Height Shift: Approximately 1"

Actual swivel range may be reduced by the TV’s width, thickness, mounting position or proximity to adjacent walls.

Low-Profile Design

When retracted, the mount positions the television approximately 2.1" from the wall. Pull the TV forward when additional swivel access, cable access or viewing-angle adjustment is needed.

Tool-Free Tilt

The screen angle can be adjusted without a separate tool after installation. Downward tilt may help improve visibility when the television is mounted above normal eye level, while upward adjustment provides additional positioning flexibility.

Cable Management

Channels integrated into the articulating arms help route and organize compatible power, HDMI and other AV cables.

Leave enough cable slack to allow the mount to extend and swivel fully without pulling on the television’s ports.

TV Compatibility

Before ordering, confirm all three requirements:

• Screen size is between 26" and 65"

• Total TV weight, without its tabletop stand, does not exceed 60 lb.

• VESA mounting pattern is between 100 × 100 and 400 × 400

Screen size alone does not determine compatibility.

Wall Compatibility

The mount is designed for installation on:

• Wood-stud walls

• Suitable solid concrete

• Suitable brick or masonry

Installation methods and hardware requirements vary by wall type. Do not attach the mount to unsupported drywall, loose masonry or an unverified wall surface.

Installation Considerations

Before installation:

1. Confirm the television’s weight and VESA pattern.

2. Identify the wall construction and stud locations.

3. Check for plumbing, electrical wiring and other hidden utilities.

4. Select hardware appropriate for the wall material.

5. Verify that the viewing location provides sufficient extension and swivel clearance.

6. Confirm that cables are long enough for full movement.

7. Follow all torque and fastener requirements in the installation manual.

Two-person installation is recommended when lifting and attaching the television.

Above-Fireplace Installation

The tool-free tilt can improve the viewing angle when a television is mounted above eye level. Before installing above a fireplace, verify that heat exposure, wall construction, clearances and the television manufacturer’s requirements are suitable for that location.

Ideal For

• Living rooms and bedrooms

• Corners and angled seating areas

• TVs mounted above normal eye level

• Home theaters and media rooms

• Wood-stud walls

• Suitable brick or concrete walls

• Installations requiring cable organization

• Viewers who want extension, swivel and tilt adjustments

Why It Stands Out

The SMF421A-B1 combines a 21" extension with a compact 2.1" retracted profile. Its dual articulating arms, tool-free tilt, post-installation leveling and integrated cable channels provide flexible positioning while maintaining a streamlined appearance.

Warranty

• 10-year warranty

Coverage is subject to SANUS warranty terms, exclusions and proof-of-purchase requirements.
