The Group "A" size of reflector was the original of the Bi-Multi range, and to a certain extent has been superseded for side streets and rural main roads
by the larger Group "AL" size referred to on other pages.
This fitting is, however, a very convenient unit as it is the smallest and lower priced reflector of its type and is also valuable where low mounting height and
other considerations do no warrant the installation of larger sizes.
The general construction of this szie follows that described in the Group "AL" section, and the various technical data, etc. is generally
applicable.
A table of the present range of angular setttings is given overleaf.
