Top jammer in its usual position, as part of a frog system rig.

An ascender that is connected via a safety cord to the D-ring, long enough for it to be connected to the rope higher than all other parts of the prusiking rig, reaching up slightly less than the furthest reach of the arms when seated. Connected to a footloop with the frog system, another prusiking system, Plummer system, Mitchell system and Jumar system. Used without a footloop with the Texas system, the hands and feet system and the double bungee variation of rope walking. Can be "handled" or "basic".
