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.

An apparatus for setting up a ladder or a step on a staircase comprises: a platform on which the ladder or the step can be set up; and a frame to support the platform on the staircase. The frame comprises at least two legs each pivotable about a common pivot axis or about respective pivot axes, wherein the common pivot axis or the respective pivot axes lie in a plane of the platform or parallel to the plane of the platform.

A work platform system having a first work platform. The system having a first bracket attached to the first scaffold and extending below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly. The system having a second bracket attached to the first scaffold and extending below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly. The system having a second work platform. The first end of the second scaffold is disposed on the first bracket and the second bracket with the first bracket and the second bracket extending between the first rung of the third leg assembly and the second scaffold. A method for using a work platform system.
