Abstract
An insulator for an electric heater employs a central elongated slot and two guide surfaces. Below each guide surface is a notch for receiving an outer convolution of a heater coil, while the central slot terminates in a notch for receiving an intermediate convolution of the heater coil. The slot engages the central convolution of the heater coil before outer convolutions engage the guide surfaces to facilitate installation of the insulator. As the insulator is inserted into the heater coil, the guide surfaces engage the outer convolutions and direct them to respective notches for securely holding the heater coil. The insulator may support a single pass of the heater coil or may be arranged to have these surfaces and notches on opposite ends to support two passes of the heater coil.
