"No modifications needed to the tarp, just need to have side pullouts. If your tarp does not already have attached pullouts, please see clip-on-tarp-pull-outs. Combined with pullouts, this pole modification increases room under your tarp.  Choose double for a set or choose single for 1 single pole mod."
