FSB’s programme of numerals and letters draws on a design that Otl Aicher recommended to our company as a headline typeface. For Otl Aicher, good legibility from a distance was all important. Our numerals and letters are made of 4 mm-thick stainless steel
, material code 1.4301. All characters feature two standardised fixing points comprising 4 mm threaded sockets. These are fitted with bolts which in turn are secured in 8 mm rawlplugs. Each character is supplied with a fixing template that also determines
the distance between characters. Custom spacing can be achieved by reducing the width of templates.
