Common Questions

What is the maximum stretch length for the MARS 34630?
The coil measures approximately 3/8" in diameter and can be stretched to a maximum length of 114.64 inches, though it can go as short as 40.12 inches depending on the KW density required by the frame.

How do I ensure the coil doesn't ground out against the frame?
Always use the provided ceramic insulators and bushings included in the kit. Ensure the coil is stretched evenly to prevent sagging, which can lead to contact with the metal casing and cause a short-to-ground.

Is this kit compatible with other brands of electric heat?
Yes, as long as the voltage (480V) and wattage (2000W) match the original specifications, this heating element restring kit is a universal solution for most open-coil electric heaters.
