monTEK Heavy Duty 40-Inch Long Arm TV Wall Mount for 60-120 Inch TVs

The monTEK Heavy Duty TV Wall Mount (model US-DS-HW1277LBK) is built for very large screens, from 60 to 120 inches. Its long arm lets a TV swing out of a corner or sit closer to a seating area, then fold back toward the wall. This page explains the numbers and what to confirm about your TV and wall.

A 40-inch reach with a heavy load limit

The headline figure is the reach: the arm extends 40 inches (about 1 m) and, according to monTEK, is specified for up to 265 lb (about 120 kg) at full extension. Load limits usually shrink as an arm extends, so a limit quoted at full reach is the figure to look for. The mount uses a dual-arm system with six steel support arms meant to keep the TV level through repeated movement, and monTEK says it passed a 4X load test.

Swivel, tilt and levelling

The screen swivels up to 60° left or right, though monTEK notes that the real range depends on TV size and placement. Tilt runs from +5° to -15° without tools or knobs, which helps with glare from windows or lamps. After the TV is up, ±5° of levelling corrects minor alignment. Folded, the mount sits 3 inches from the wall.

TV size and VESA pattern

The listing says the mount fits most LED, LCD, OLED, QLED, 4K and 8K TVs from 60 to 120 inches, and VESA patterns from 200x200 to 900x600 mm. VESA is the standard spacing of the mounting holes on the back of a TV. Always confirm the pattern and weight in your TV's manual, as screen size alone does not guarantee a fit.

Walls and studs

Large TV mounts put significant force on the wall. The listing states it installs on 12, 16, 18 or 24 inch wood stud spacing, solid concrete or brick, and that it must not be mounted on drywall alone. A stud finder, the right fasteners and the instructions are essential, and a professional installer is worth considering if you are unsure about your wall.

Installation details

The main articulating assembly arrives pre-assembled. A quick-release locking mechanism makes it easier to secure or remove the TV. The listing includes mounting hardware, a template, a bubble level and illustrated English instructions. At about 41 lb for the mount alone, plus a very large TV, monTEK recommends two-person installation.

Who it suits

This mount suits large living rooms, home theatres, corner installations, open-plan spaces and conference rooms, which monTEK names, where the screen must serve different seating areas. For a mid-size TV that stays put, a shorter and lighter mount is simpler.
