A piton (/ ˈpiːtɒn /; also called pin or peg) in climbing is a metal spike (usually steel) that is driven into a crack or seam in the climbing surface using a climbing hammer, and which acts as an anchor for protecting the climber against the consequences of falling or to assist progress in aid climbing.

Pitons (or pegs as they are often known in Britain) are, since the advent of modern wires, nuts and camming devices, seldom used in the UK for summer rock-climbing any more. However they are an important tool in winter and alpine climbing where narrow cracks may be choked with ice and other protection hard to find.

What is a climbing peg board? Climbing Peg Boards are wooden boards with holes in them. Pegs or handles can then be slotted into the holes. And by holding onto the pegs you can climb your way around the board moving from hole to hole. There are different sizes and shapes or peg board available and you use them for a variety of exercises.

Peg boards are wall mounted, wooden boards which are filled with holes around 4cm deep. They are used with special handles which slot into the holes. You then use the handles to climb around the board.
