What are spreader bars?
Spreader Bars are basically the bars that “spread” the hammock open. One spreader bar is located at each end of the hammock bed, partitioning the bed from the end strings. The bars serve as supports in keeping the bed open and creating a flatter surface even when the hammock is in use. Usually they are composed of different types of wood, aluminum or virtually unbreakable poly. You are most likely to see spreader bars in rope and fabric hammocks.
