    Metalbest 6T-SB Reviews

    • Is this piece what I need to go through a cathedral ceiling, does it actually have pipe in it, and what are the dimensions?

      A. The Metalbest 6T-SB is the piece you would need to get your pipe through cathedral ceilings. It does not have pipe running through it, it simply keeps your clearances while you are passing through your ceiling. It measures 24" tall and is 14.25" deep and wide.
