A bar hanger assembly is used to couple a housing to a support structure. The bar hanger assembly may include a bar hanger holder to mechanically couple the bar hanger assembly to the housing, such as a junction box, a can housing, or a frame. The bar hanger holder may define a channel to mechanically guide and support a pair of bar hangers. The bar hangers may be mechanically coupled together in a telescoping manner such that the first bar hanger is slidably adjustable with respect to the second bar hanger. The bar hanger holder and each bar hanger may physically contact one another and, in some instances, generate a compressive force to substantially reduce unwanted play. Each bar hanger may include a bar hanger head to couple the bar hanger assembly to various types of support structures, such as a T-bar, a stud, a joist, or a frame.
