{"product_id":"internal-joist-ceiling-kit-cma165","title":"Internal Joist Ceiling Kit","description":"\u003cp\u003eThe Chief CMA165 Internal Joist Ceiling Kit simplifies projector installations in both new construction and finished ceiling environments. This adapter kit allows an installer to suspend a projector between existing ceiling joists using only a 4\" hole. The kit includes a junction box mounting brace and a 5\" round plate designed to mate with standard fan mounting junction boxes. The plate is compatible with 1.5\" NPT extension columns and provides an adjustable extension range of 16\" - 24\" (40.64cm - 60.96cm). This solution is specifically designed to accommodate common ceiling layouts by expanding to fit either 16\" or 24\" joist spacing. With a weight capacity of 50 lbs (22.7 kg), this kit offers a stable mounting method similar to a standard ceiling fan installation.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAdapts to 1.5\" NPT extension columns via a 5\" round plate\u003c\/li\u003e\n\u003cli\u003eFits joist spacing of 16\" or 24\" with an adjustable extension of 16\" - 24\" (40.64cm - 60.96cm)\u003c\/li\u003e\n\u003cli\u003eSupports projector weight up to 50 lbs (22.7 kg)\u003c\/li\u003e\n\u003cli\u003eTAA compliant for government and specialized contract projects\u003c\/li\u003e\n\u003cli\u003eMounts to standard fan mounting junction boxes through a 4\" ceiling hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuestions\u003c\/h2\u003e\u003ch3\u003eWill the CMA165 fit my existing ceiling joists?\u003c\/h3\u003e\u003cp\u003eThe kit is designed to expand to accommodate either 16\" or 24\" joist spacing.\u003c\/p\u003e\u003ch3\u003eWhat type of extension column does the CMA165 require?\u003c\/h3\u003e\u003cp\u003eThe 5\" round plate included in this kit adapts specifically to 1.5\" NPT extension columns.\u003c\/p\u003e\u003ch3\u003eWhat is the maximum weight capacity for this projector kit?\u003c\/h3\u003e\u003cp\u003eThe CMA165 has a weight capacity of 50 lbs (22.7 kg).\u003c\/p\u003e\u003ch3\u003eCan I use this with a standard junction box?\u003c\/h3\u003e\u003cp\u003eYes, the ceiling plate is designed to mate with a standard fan mounting junction box.\u003c\/p\u003e\u003ch3\u003eWhich document should I use for the submittal process?\u003c\/h3\u003e\u003cp\u003eThe CMA165 Technical Drawing (PDF) is available for use in project submittals.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSpecifications are supplied by the manufacturer.
