16 DIN range of pantograph wiper arms forms part of a family of new arms produced
by Matador which include 12 DIN, Knurled Driver and Square Drive configurations
as related on separate data sheets. In this case the pantograph wiper arms will
directly interchange with those currently used in railway applications and can
be supplied with bridge widths of 44, 50 and 60mm and various blade clip widths
including 10.8 and 13.6mm amongst others.

the earlier standards of wiper arms. The wiper arms are finished in a semi-matt
black colour process achieved by the electro-phoretic paint deposition process
coupled with a further protective surface that prevents discolouration by
