Internal Joist Ceiling Kit
Internal joist ceiling kit for projector installations, adapts to 1.5" NPT columns with a 50 lbs capacity
The 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.
