The Cape hanger is built in the Achievement Gallery of a player-owned house as a place where players can show off the capes they own. Players can use either a skillcape or a fire cape on the cape hanger. The display can be admired, making the player perform the same animation as praying at an altar.
A player will need both the hood and cape of the skillcape in order for it to be on display. In addition, untrimmed skillcapes that are mounted on the cape hanger will become trimmed upon achieving level 99 in another skill.
