IN its production, the essential features, not only of immediate and reliable check, but perfect resistance to the highest frictional
heat, has been provided for. Manufactured only from guaranteed 100% pure asbestos reinforced by metallic strands
and containing no COttOH or other fibre perishable by heat, woven solid in all thicknesses up to one inch, transmitting

a sure grip and engagement, soft as velvet and pliant as a hand grasp, it easily outlives many times all
other braking media—whether of metal, wood or other combinations.

Used by hundreds of Collieries, Forges, Engineering Works, etc., for Winding Drums, Brake
Posts, Drift or Transport Winches, and all Power Clutch and Brake Gears ; also for
Trolleys, Cranes, Hauling Machinery, and Electro-mechanical Brakes fitted to
Hoists, Centrifugal Machines, etc., above or below ground or water.
