Q:I'm moving the location of registerbox in my house. I have 6in duct work and plan to use a baseboard diffuser. I need a 90 degree box to end the duct and enter the diffuser. as it will be a baseboard diffuser most appear to be 3 inches wide. the old duct work in my house is 10x2.5x6 but I cannot find a replacement that size. This 10x4x6 is the closest I've found, but will not fit as the hole would stick out below the baseboard diffuser. Am I misunderstanding something?
