This is a Harken roller furling system that can be used for daysailing or single-handed sailing.  This is NOT class legal for racing.  The kit includes the Harken furling drum, forestay tang, wire, shackle, U-bolt, eye strap, Harken micro cam cleat with wedge and fairlead, line (5/32 super prestretch), and fasteners.  If you are going to repurpose a jib you already own the jib will have to be modified by having the batten removed and a UV panel added.  If you would like to purchase a roller furling jib with a UV panel see link below.
