MantelMount MM340 Above Fireplace Pull Down TV Mount - Full Motion

In this review the MantelMount MM340 stands out as a purpose-built above-fireplace TV mount for 44' to 80' TVs that need reliable full-range motion and vertical travel. The biggest reason to choose it is the combination of smooth pull-down operation and patented auto-stabilizing technology that keeps large screens level while allowing up to 27' of vertical travel and 30 degrees of swivel. For rooms with deep mantels or awkward sightlines, the MM340 delivers motion and balance most competing mounts do not.

Key Features

• Full-range motion: Offers up to 27' vertical travel and 19' off-the-wall to position a TV for comfortable viewing from different seating areas.
• Wide swivel and clearance: 30 degrees of left and right swivel and up to 18' maximum mantel clearance so it adapts to many room layouts and deep mantels.
• Patented stabilization: TV auto-straightening and gas piston auto-stabilization keep the screen level after adjustments for a cleaner, professional look.
• Practical controls: Pull down handles and adjustable motion stops allow easy operation and limiter settings to protect the TV and surroundings.
• Solid construction: Heavy-gauge steel design supports TVs from 20 to 90 lbs and accommodates VESA patterns up to 600mm x 600mm for larger displays.
• Confidence features: UL listing, limited lifetime warranty and a 100% guarantee provide assurance for long-term installations.

Who It's For

The MM340 is ideal for homeowners who want to mount a 44' to 80' TV above a fireplace or high shelf and still achieve comfortable viewing angles; its vertical travel and swivel make it especially useful in living rooms where sightlines change between seating areas. Installers and DIYers who value a stable, heavy-duty mount with cable management and patented auto-straightening will appreciate the engineering and build quality.

It is less suitable for very lightweight TVs under 20 lbs or installations that cannot reach studs up to 24' apart. Buyers who need an ultra-low-profile fixed mount or who cannot accommodate the 7.25' depth when retracted should consider a different style.

Pros & Cons

Pros

• Well-built steel construction supports large screens while remaining stable during motion.
• Patented TV auto-straightening and gas piston stabilization make adjustments smooth and keep the display level.

Cons

• Installation can require two people and careful anchoring to reach studs up to 24' apart for secure mounting.
• The mount weighs 29 lbs and projects up to 7.25' deep when stored, which may not suit very shallow mantel areas.
