The Regitell™ is a temperature-monitoring decal for air conditioning-heating registers. It is said to eliminate the need to climb a ladder to check ceiling or wall register temperatures. The decal indicator is placed on the metal surface of the register, and within minutes after the hvac system starts operating, it will visually indicate whether the register is venting the proper cold or hot air. A blue C on the decal means cold; a red H stands for hot. FrontStage Enterprises Inc., 103 Robertson Blvd., Beverly Hills, CA 90211; 877-734-4835; 310-657-3569; 310-657-3182 (fax).
