Adjustable between 30,5 and 45,7 cm, it gives installers precise drop control to position the display or projector at exactly the right height without structural alterations. Built from aluminium and engineered around Chief's notched Speed-Connect system, it is well suited for corporate boardrooms, classrooms, and any AV installation where ceiling height varies or retrofitting is required. The column accepts any Chief 1.5\" NPT accessory, making it a versatile building block in a wider Chief mounting ecosystem. TÜV certified and UL listed, it carries a 10-year limited manufacturer warranty.\u003c\/p\u003e\u003cdiv style=\"overflow: hidden; margin-bottom: 28px;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0648\/8522\/7743\/files\/Checkmark-ikon.png?v=1780246476\" alt=\"Tool-Free Height Adjustment in 2,5 cm Steps\" style=\"float: left; width: 75px; height: 75px; object-fit: contain; margin: 5px 20px 8px 0;\"\u003e\u003cp style=\"margin: 0 0 6px 95px;\"\u003e\u003cb\u003eTool-Free Height Adjustment in 2,5 cm Steps\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 0 95px;\"\u003eThe CMS012018 uses Chief's notched Speed-Connect design, which allows the column length to be changed in 2,54 cm (1\") increments without disassembly. In practice this means an installer can dial in the correct drop height — anywhere between 30,5 and 45,7 cm — while the mount is already in place overhead, rather than having to lower the entire assembly to make the change. A set screw locks the chosen position once confirmed, eliminating play or vibration. For end users this translates to a display or projector that sits exactly where it needs to be, with no re-installation risk if the room layout changes later.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv style=\"overflow: hidden; margin-bottom: 28px;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0648\/8522\/7743\/files\/Checkmark-ikon.png?v=1780246476\" alt=\"Integrated Flow-Through Cable Management\" style=\"float: left; width: 75px; height: 75px; object-fit: contain; margin: 5px 20px 8px 0;\"\u003e\u003cp style=\"margin: 0 0 6px 95px;\"\u003e\u003cb\u003eIntegrated Flow-Through Cable Management\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 0 95px;\"\u003eAn integrated cable port on one end of the column channels signal and power cables through the interior of the pipe rather than along the outside of the structure. This keeps the finished installation visually clean and reduces cable stress at connection points. In practice it means no exposed cable runs dangling from a ceiling-mounted projector — a meaningful outcome in corporate or educational spaces where aesthetics and cable integrity both matter. Combined with compatible Chief cable covers (e.g. CMA274), the result is a tidy, professional finish that is also easier to service.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv style=\"overflow: hidden; margin-bottom: 28px;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0648\/8522\/7743\/files\/Checkmark-ikon.png?v=1780246476\" alt=\"226,8 kg Load Rating — Aluminium Build\" style=\"float: left; width: 75px; height: 75px; object-fit: contain; margin: 5px 20px 8px 0;\"\u003e\u003cp style=\"margin: 0 0 6px 95px;\"\u003e\u003cb\u003e226,8 kg Load Rating — Aluminium Build\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 0 95px;\"\u003eDespite its lightweight aluminium construction, the CMS012018 is rated to support up to 226,8 kg (500 lbs), which far exceeds the weight of virtually any commercial projector or flat panel display it will be used with. The aluminium material also simplifies on-site handling compared to steel pipes of similar strength, reducing installation effort when working at height. TÜV certification and UL listing independently validate the structural claims, giving integrators documented evidence for building compliance requirements.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv style=\"overflow: hidden; margin-bottom: 28px;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0648\/8522\/7743\/files\/Checkmark-ikon.png?v=1780246476\" alt='Universal 1.5\" NPT Compatibility' style=\"float: left; width: 75px; height: 75px; object-fit: contain; margin: 5px 20px 8px 0;\"\u003e\u003cp style=\"margin: 0 0 6px 95px;\"\u003e\u003cb\u003eUniversal 1.5\" NPT Compatibility\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 0 95px;\"\u003eBoth ends of the column carry standard 1.5\" NPT threads, making it compatible with the full Chief ecosystem of ceiling plates (CMA101, CMA105, CMA110, CMA115, CMS440 etc.) and projector\/display mounts. It can also be coupled with a second column via the CMA270 threaded pipe coupler for extra drop depth. This universality means a single SKU covers a wide range of project configurations, reducing the number of line items an integrator needs to stock and simplifying both quoting and on-site troubleshooting.\u003c\/p\u003e\n\u003c\/div\u003e\u003chr\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eFeatures\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand compatibility\u003c\/td\u003e\n\u003ctd\u003eChief\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eSpeed-Connect\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eMetal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct colour\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum weight capacity\u003c\/td\u003e\n\u003ctd\u003e226.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertification\u003c\/td\u003e\n\u003ctd\u003eTAA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eWeight \u0026amp; dimensions\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e59 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e59 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e457 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.36 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eLogistics data\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr\u003e\n\u003ctd\u003eHarmonized System (HS) code\u003c\/td\u003e\n\u003ctd\u003e85299097\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Chief","offers":[{"title":"Default Title","offer_id":53404525494608,"sku":"841872092676","price":537.1,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/8522\/7743\/files\/7e6e2473b5b3b12a39751e5a855668ce_d3df8b7c-fe71-4945-97cd-e7a1ba5dc2af.jpg?v=1786962448","url":"https:\/\/www.intersign.dk\/products\/npt-threaded-adjustable-extension-column-12-to-18-305mm-457mm-black","provider":"Intersign","version":"1.0","type":"link"}
