Abstract
A duct heater includes end brackets by frame bars. The end brackets are formed into a geometric shape whereby only corners of the bracket engage an inner suface of the duct. Assembly is facilitated by providing the end bracket as thin, flat strips having narrower and wider sections. The frame bars are attached to the wider sections, and when the strips are bent to form a closed geometric form, the thinner sections are curved to form duct-engaging corners while the wider sections remain substantially straight. Insulating supports are attached to the frame bars, and a heater coil is attached to the insulating supports. The structure may be easily slid into a duct because only the corners of the end brackets contact the duct. Thus, a method for forming the heater brackets and attaching heater elements is set forth.
