Chief CMS0406, 121.9-182.9 cm, Adjustable — Adjustable ceiling extension column for projector mounts
The Chief CMS0406 is a heavy-duty adjustable extension column designed for professional ceiling-mounted projector installations. It accommodates drop heights from 121.9 to 182.9 cm, making it ideal for spaces with high ceilings such as auditoriums, lecture halls, conference rooms, and houses of worship. The column features 1½" NPT threaded connections on both ends, ensuring broad compatibility with Chief ceiling plates and projector mounts within the Speed-Connect ecosystem. Finished in black, it blends discreetly into standard interior environments. TAA compliant, it suits government and publicly funded installations. The adjustable design means a single SKU covers a wide range of drop requirements, simplifying specification and reducing the number of parts needed on-site.
Wide Adjustable Drop Range
The CMS0406 spans 121.9 to 182.9 cm, giving installers a single column that covers a substantial range of ceiling heights without the need to stock multiple fixed-length pipes. In practice this means a projector can be fine-tuned to the correct throw distance and image height after the ceiling plate is already installed — useful when exact ceiling heights are unknown at the time of ordering, or when the projector model changes between specification and installation. It eliminates the guesswork of pre-cutting fixed pipes and reduces the risk of costly re-orders.
Universal 1½" NPT Threading
Both ends of the CMS0406 carry standard 1½" NPT (National Pipe Thread) connections. This is the de facto standard thread size across Chief's ceiling plate and projector mount lineup, meaning the column works with virtually any Chief CMA ceiling plate or projector mount that uses the same thread spec — and with many third-party accessories built to the same standard. For installers managing multi-room or multi-brand deployments, this broad compatibility reduces the need for adapters and simplifies inventory. It also makes future projector upgrades straightforward: the column stays in place and only the projector mount changes.
TAA Compliance for Government Projects
The CMS0406 is Trade Agreements Act (TAA) compliant, meaning it meets U.S. federal procurement requirements for country of origin. For system integrators working on government, military, or publicly funded education projects, TAA compliance is often a contractual requirement that rules out non-compliant alternatives. Specifying a TAA-compliant column from the outset avoids the risk of having an installation rejected during compliance review, saving time and reputational risk on sensitive projects.
