Supco Duct Heater Coil Kits are made of nichrome heavy gauge construction for long lasting durability. Welded terminal bolts for low resistance and longer life. Complete kits include close wound coil to fit many applications, two male and two female bushings, terminal screws, nuts and washers to make proper repairs.

When stretching coils measure length needed and stretch new coil slightly shorter. After installation, cycle with the heater on and allow full operation for 5 minutes.
