<p>The bracket holder is for a multiple plate-type heater, and comprises a standpipe with foot and holders. The top holder has a headpiece (8) fitting in the standpipe (7), and supporting two wings (15,16) hinging sideways. The headpiece can be of plastics, with a boss (10) fitting in the pipe and from which two sidewalls (12) extend upwards. These are joined by an end rib (13) so as to form a chamber (14) open at the side for the wings, whose spindles (17) work in bearings in the sidewalls. The boss can have a flange (11) by which it rests on the top end of the pipe.</p> |
