Chief WM220AUS

The Chief WM220AUS is a complete short-throw projector wall mount kit designed for conference rooms, classrooms, and training spaces where a projector must be mounted close to a wall. The kit combines the WM220S dual-stud telescoping extension arm with the RSMAUS Universal Mini RPA Elite projector mount, delivering an all-in-one solution engineered for precision, flexibility, and strength. Its universal interface accommodates the vast majority of projectors on the market today, and the kit ships with hardware for wood stud, steel stud, and concrete wall construction, making it a genuine one-stop solution for most installation environments.

Quick-Connect System Cuts Install Time

The WM220AUS uses Chief's innovative quick-connect system to dramatically reduce the time spent hanging a projector on site. The arm and projector mount couple together without hand tools for the final attachment step, so a single installer can position and lock the projector accurately in minutes rather than wrestling with it against the wall. For integrators running back-to-back installations in multi-room rollouts — such as a school district upgrade or a corporate campus fit-out — this translates directly into fewer labour hours per room and less disruption to the end client's schedule.

Micro Height and Leveling — No Remounting Needed

Chief was first to market with a micro height and leveling adjustment on a wall-mounted short-throw arm, and the WM220AUS carries that feature forward. After the projector is physically installed, the image can be raised, lowered, or leveled by small, tool-accessible increments without detaching the arm from the wall. In practice this means a miscalculated stud position or a slightly out-of-plumb wall does not require a complete reinstall — the installer corrects the image on the fly. For end users this delivers a precisely squared, level picture that stays locked in position over time.

Precise short-throw mounting. Zero reinstalls.

RPA Elite Micro Alignment: Roll, Pitch, and Yaw

The bundled RSMAUS Universal Mini RPA Elite projector mount provides independent micro-adjustment on all three axes — roll, pitch (±3°), and yaw. Each axis is adjusted separately using small set screws, giving the installer surgical control over image geometry without needing to shift the arm or the projector body. This is especially valuable in rooms with unusual ceiling heights, non-flat projection surfaces, or strict alignment tolerances (such as boardrooms with fixed-frame screens). Once set, the adjustments hold position securely under the projector's weight, minimising ongoing maintenance.

Integrated Lateral Shift for Dual-Stud Applications

Because wall studs rarely align perfectly with the projector's ideal optical axis, the WM220AUS includes an integrated lateral shift mechanism. This lets the installer offset the projector horizontally after the arm is fixed to the studs, ensuring the lens is centred on the screen without relocating the wall anchors. The adjustment is built into the arm rather than added as a separate accessory, keeping the installation compact and reducing the number of components that need to be specified or sourced.

Multi-Substrate Hardware Included

The kit ships with mounting hardware for wood stud, steel stud, and concrete wall construction, so installers do not need to specify or separately procure substrate-specific fixings before visiting site. This broadens the range of venues the product fits without additional procurement steps — from timber-framed classrooms to steel-framed commercial buildings and solid concrete walls in older facilities. Fewer site unknowns means fewer return visits and more predictable project costs.

Layered Security for Public and Semi-Public Spaces

The WM220AUS implements Chief's All-Points locking hardware alongside four projector mount keyed locking options (key sets A, B, C, D). All-Points locking secures the arm to the wall plate so the assembly cannot be detached without a key, while the projector mount keyed locks prevent the projector from being removed from the mount. This layered approach is appropriate for education, hospitality, and any semi-public space where projector theft is a realistic concern, and allows large multi-site deployments to use a single key type across all rooms for simplified facilities management.

Integrated Cable Management for a Clean Finish

Cables run through dedicated channels built into the arm, keeping power and signal leads concealed and protected along the full length of the extension. A tidy installation reduces the visual clutter often associated with wall-mounted projection in presentation rooms, and protects cables from accidental snagging during projector servicing. For permanent installations in visible spaces such as reception areas or board rooms, this built-in cable routing removes the need for separate cable conduits or trunking along the mount.
