The Savage Multiple Polevault Support System is lightweight, yet sturdy enough to support 3 rolls of paper or cloth up to 9' wide, or 1 roll of paper 12' wide.

Its aluminum uprights rise to a maximum height of 9.75'. Each of its 3 crossbars telescope from 5.25 to 12.6'.

For extra safety -- sandbags are available as accessories to secure the setup around active children. 
And, don't forget a clamp or two, to secure your roll of paper, or to drape your cloth background more creatively.
