The invention relates to a heater duct especially
for vehicles and more particularly for passenger
frames 8 at any desired locations along its longi
tudinal extent. The cold and hot water pipes I4,

a housing arranged along the corner of the ñoor
and a vertical wall of the room to be heated, which
housing contains the heater elements such as a
steam or hot Water radiator, though other types

A panel strip I 6 and the ilange along themargin
of the horizontal arm I'I of another generally
angle-section panel strip are secured by screws I8
to said frames 8. The other arm I9 of the last
mentioned panel strip extends upwardly and has
its upper margin secured by screws 20 to the panel
