A
term used to describe a
very small nut (aka
chock) used in
Trad Climbing. Another name for an
rp is also
peanut. Most often these are used for
crack climbing when the
crack is too small to place a "
normal" sized
nut. Because of the
small surface area of the rp, which causes a
decrease in
reliability they are often placed with
several other's in the
general area as
backup.
