Large manual height-adjustable mobile AV cart
Chief LPAUB
The Chief LPAUB is a large Fusion® mobile AV cart designed for flexible display deployment in corporate boardrooms, classrooms, and meeting spaces. Built around Chief's proven Fusion® platform, it accommodates flat-panel displays from 42 to 86 inches and supports landscape or portrait orientation, making it adaptable to a wide range of presentation scenarios. Its rounded, black-finished construction projects a professional aesthetic that blends comfortably into modern environments. The cart is engineered for reliable daily use: a single operator can reposition the screen height anywhere between 127 and 177,8 cm from floor to display centre, using either the integrated turn knob or a standard power drill with a 1/2" hex bit. Four pre-assembled heavy-duty casters — two of which lock — make the unit safe to roll between rooms and secure when in use.

Tool-Free Single-Operator Height Adjustment
The LPAUB's height adjustment mechanism lets one person raise or lower the display anywhere between 127 and 177,8 cm (floor to display centre) without calling in a second installer. Turning the integrated knob by hand is sufficient for routine repositioning; for faster changes — or when the mounted display is particularly heavy — a standard power drill fitted with a 1/2" hex bit does the job in seconds. This matters in corporate or education settings where the cart is moved between rooms with different audience sizes or seating arrangements. End users can reconfigure the screen height themselves on the fly, eliminating the need to involve facilities or IT staff for every room changeover.

Centris Technology: Tilt and Roll After Installation
Chief's Centris Technology gives the cart's head assembly independent tilt (±5°) and roll adjustment via simple knobs, so image geometry can be corrected after the display is mounted and the cart is in its final position. In practice, this means that even on slightly uneven floors — common in older office buildings or portable classroom setups — the displayed image can be levelled without moving the cart or re-hanging the screen. End users benefit from a consistently straight, professional-looking picture without having to call back the installer.
One person. One knob. Any height from 127 to 177,8 cm.

High Load Capacity with VESA Versatility
With a rated capacity of 90,7 kg and compatibility with VESA mounting patterns from 200×200 mm up to 800×400 mm, the LPAUB can carry virtually any commercial large-format display in the 42–86-inch class — including heavier all-in-one collaboration displays and video-bar-equipped screens that are increasingly common in huddle and conference rooms. Portrait orientation is also supported for screens at least 68,6 cm tall with a VESA pattern of 400×400 mm or smaller, opening up digital-signage and kiosk-style use cases without requiring a separate portrait stand.

Integrated Cable Management Along the Full Column
Flexible cable covers run the entire length of the column and allow cables to be laid in at any point — not just at the top or bottom. This means HDMI, power, and USB runs stay concealed and protected regardless of where the height is set, and there is no need to re-route cables after a height adjustment. In shared or public spaces, tidy cable management reduces trip hazards and gives the installation a finished look that reflects well on the deploying organisation.

Mobile Yet Stable: Pre-Assembled Locking Casters
The LPAUB ships with four heavy-duty casters already installed, so the cart is ready to roll straight out of the box. Two of the four casters lock, providing a stable, fixed footprint once the cart is positioned — an important safety feature when a large, heavy display is mounted at maximum height. The combination of mobility and lockable stability makes the cart equally suited to permanent room installations that occasionally need to be moved, and to shared-cart workflows where the same unit rotates between multiple rooms or venues throughout the day.
