Modulars come in seven diameters (4", 6", 8", 10", 12", 14", 16"), each fitting a 2" range (e.g., 6" fits 4-6", 8" fits 6-8"). Available in three widths: 2.25", 4", 6". Use the calculator to generate the correct combinations for each zone.

Measure the full circumference of your heater band, ensuring you include any terminals or junction boxes. This will help determine the maximum diameter the blanket needs to cover.
