Product Description

Adder for 120 Volt.

Adders are used to attach one sheet of Heating Film to another, when a thermostat cold lead connection is not required.  Adders are available in 120 volt and 240 volt configurations.  To add a single sheet of Heating Film to a 120 volt system, an “A-120” (A indicates one additional sheet, 120 indicates the voltage) would be required. To add two sheets to an existing sheet, use an A2. To add three sheets, an A3 will be required. An A4 will connect up to four sheets to an existing sheet or sheet set.
