A fusible sign support has a hanger adapted for connection to an overhead support and a bracket adapted for connection to a sign, The hanger and the bracket are secured to one another by a fusible, eutectic bonding material which liquefies at a selected, elevated tempera- ture. When the bonding material liquefies the hanger and bracket separate enabling the sign to fall. The construc- tion makes possible removal of a sign from the path of water emitted from a fire sprinkler head. The liquefica- tion of the bonding material occurs at a temperature lower than that at which the sprinkler head is activated.
