Reserve static line
The RSL is a lanyard connecting one or both of the main parachute risers to the reserve ripcord.
However, proper emergency procedures require the reserve ripcord to be pulled in the event that the RSL is disconnected or not functioning correctly.
[1] An RSL also offers protection in the event a jumper cuts-away but does not (or can not) reach for the reserve deployment handle.
The RSL can be disengaged by a skydiver in situations where it is desirable to detach the main parachute without deploying the reserve.
The RSL attaches to the risers through a small metal loop that will disconnect when a fabric tab is pulled.
