Chief CMS0305W, 91-152 cm, Adjustable — Adjustable ceiling extension column, white
The Chief CMS0305W is a professional adjustable extension column designed for ceiling-mounted projectors and flat panel displays in commercial AV installations. Available in white to blend with light-coloured ceilings, it is built for integrators who need a flexible, reliable drop solution for conference rooms, classrooms, and other professional environments. Compatible with any standard 1.5" NPT ceiling plate or accessory, the column allows installers to fine-tune drop height on site without tools or full disassembly — a decisive advantage on complex or multi-phase projects. Built from high-quality aluminium, UL Listed, and TAA Compliant, it is backed by Chief's 10-year warranty.
Tool-Free Height Adjustment on Site
The CMS0305W uses a notched design that lets installers change the column length in 2,54 cm steps across the full 91–152 cm range without taking the system apart. In practice this means the drop height can be dialled in at the point of installation — or corrected later if ceiling conditions, furniture layout, or projector throw distance change — without scheduling a full disassembly visit. For end users in spaces that get reconfigured periodically, such as multi-purpose rooms or lecture halls with movable seating, this translates directly into lower service costs and faster adjustments.
Universal 1.5" NPT Threading
Both ends of the CMS0305W are threaded to the industry-standard 1.5" NPT specification, making it compatible with virtually the entire range of Chief ceiling plates, spiders, and pipe accessories, as well as third-party mounts that share the same standard. This universality is important at design stage: it keeps the column usable across a wide variety of projector and display configurations without locking the installation into a proprietary ecosystem. End users benefit from a system that can be extended or adapted over the product's lifetime without replacing structural hardware.
Integrated Flow-Through Cable Management
An integrated routing port allows signal and power cables to be fed through the interior of the column rather than run externally. The result is a visually clean installation — no cable bundles visible along the drop — which matters both for professional appearance and for safety in public-facing or high-traffic spaces. Cables routed internally are also better protected from accidental pulling or tampering, reducing the risk of connection failures during use.
Vibration Damping for Stable Projection
A set screw is included specifically to counter building vibrations that can cause a suspended projector or display to oscillate — a common issue in environments near HVAC systems, heavy foot traffic, or mechanical plant rooms. Keeping the image stable is directly relevant to the audience experience in classrooms and boardrooms, where even minor wobble makes text hard to read. The set screw adds rigidity to the column joint without complicating future height adjustments.
226,8 kg Capacity with 10-Year Warranty
The column is rated to 226,8 kg, which comfortably covers even large-format laser projectors and heavy commercial displays. UL Listing confirms that the load rating has been independently verified to a recognised safety standard — a requirement for many institutional and government projects. The 10-year warranty signals long product lifetime and reflects Chief's confidence in the aluminium construction, reducing the risk of mid-lifecycle replacement costs for the end customer.
