It is three times more durable than chilled iron—five times more durable than leather. It cannot carbonise, cannot slip nor seize, cannot spark, cannot throw off metal dust. Ferodo fabric has been exclusively used for many years by the London and Paris Underground Railways. It is used on cranes and winches, winders and haulages, hoists and friction drives, clutches for every purpose, on every duty where an efficient friction surface is essential. Insist on genuine “ Ferodo ’’ fabric for brake and clutch linings. FRICTION SURFACES.
