Mattamy is installing Insulated Ceiling Electrical box in upper floor, as shown in the picture, any one know what do i need to do to hang the Ceiling fan / Chandelier after the closing,
Do i need to add reinforcement (if Yes how can i do it) or completely replace it with metal one (like 2nd Picture), my concern if i replace it with metal one do i need to cover it with some thing since its in Attic
Thanks
