Abstract: A support apparatus to secure a mass loaded vinyl roll on a scaffold above a ground surface dispenses mass loaded vinyl from the roll with enhanced efficiency for an application on a wall. The support apparatus includes a frame assembly having a pair of upright legs coupled to a generally horizontal bar, each upright leg in the pair of upright legs having a top end with a U-shaped member coupled thereto, a pair of clamps mounted to the horizontal bar to secure the frame to the scaffold, and a spool bar coupled to the U-shaped members of the pair of upright legs and designed to secure the mass loaded vinyl roll thereon.
