A regular net
The net (also called goal) is a 6'x4' (1.8x1.2 m) metal frame that supports a cloth net in which players mush shoot the puck in order to score goals. The two vertical tubes extending from the ice are called the goal posts, while the tube that connects both posts at the top of the goal is called the crossbar.
The back of the goal frame is covered in a net to catch pucks shot into the goal. The goal posts and crossbar are painted red. The inside part of the goal frame is padded to keep pucks that enter the net from rebounding out.
The goal frame is moored to the ice by flexible pegs; these keep the goal in its place in normal time, but allow it to move freely in case a player crashes into it. In many multipurpose rinks however, it is rather a metal pin protruding about a quarter of an inch that serves this purpose, as the pegs require bigger holes drilled into the ice, holes an ice resurfacer can't repair; this would leave this part of the ice dangerous when the goals are removed in order to allow other activities like free or artistic skating.
