Chief WM120AUS

The Chief WM120AUS is a medium short throw projector wall mount kit designed for AV installers who need a precise, secure and clean mounting solution for compact short throw projectors in classrooms, boardrooms and auditoriums. The kit combines the WM120S single-stud extension arm with the RSMAUS Universal Mini RPA Elite projector mount, delivering the flexibility to accommodate different projector brands and future replacements. The arm attaches to a single wall stud, keeping the installation clean and the projector positioned above the audience. Its micro height, pitch and leveling adjustment system enables exact image alignment once installed, reducing on-site setup time significantly.

Quick-Connect Single-Stud Installation

The WM120AUS mounts via a single wall stud using an innovative quick-connect system that accepts wood stud, steel stud and concrete anchor hardware — all included in the box. Avoiding a double-stud requirement dramatically increases the number of viable mounting locations on a given wall, which is particularly valuable in classrooms or conference rooms where structural studs do not always align with the ideal projector position. The quick-connect design also means the arm can be removed and reinstalled without specialist tools, making future projector swaps or moves straightforward for the end-user's facilities team.

Precise MicroZone Image Alignment

Chief's MicroZone adjustment system provides independent micro roll, pitch (±3°) and height control without requiring the projector to be repositioned on the mount. Once the arm is on the wall, the installer can dial in a perfectly squared, level image in minutes rather than the repeated remove-and-reposition cycle that older mounts required. This is especially relevant with short throw projectors, where even a small angular deviation produces a noticeably skewed image at close range. Paired with the included RSMAUS Mini RPA Elite mount, which also offers Centris Technology for fingertip repositioning, the combined system gives the end-user a stable, precisely aligned picture throughout the projector's service life.

One stud. Full alignment control. Zero cable clutter.

Integrated Cable Management

Cables route through the top of the mount arm itself, concealed from view and protected from accidental snagging — without requiring any additional cable tray accessories. In education and corporate environments where displays and cabling are frequently inspected for safety and tidiness, this built-in channel means the finished installation looks professional and audit-ready from day one. It also reduces the risk of cables being inadvertently disconnected when the projector is adjusted or serviced, contributing to fewer support calls.

Multi-Level Security for Shared Spaces

The WM120AUS incorporates All-Points locking hardware that secures the arm at every adjustment point, preventing accidental movement in high-traffic environments. In addition, the included RSMAUS projector mount supports four keyed locking options (A, B, C and D), allowing institutions to match locks across a campus while still keeping different zones independently keyed. For schools, museums or hospitality venues where projector theft or tampering is a realistic concern, this layered security approach is a strong selling argument that competitors in the same price range rarely match.

Universal Projector Compatibility and Future-Proofing

The bundled RSMAUS Universal Mini RPA Elite mount uses a universal interface that accommodates a wide range of projector mounting hole patterns. It is compatible with Chief RPA standard, RPA Elite, RPA Mini and RPA Mini Elite mounts, while being 33% smaller than the standard RPA yet retaining a full 11.3 kg weight capacity. This makes the WM120AUS a sound long-term investment: when the end-user upgrades or replaces their projector, the wall arm and mount can typically be retained, avoiding the cost of a full reinstallation. Centris Technology automatically adjusts tension to match the specific projector's weight, maintaining consistent resistance across brands and models.
