         highest degree of load securement on the
         market. This innovative product is part
         of Columbus McKinnon’s commitment to
         designing  the  safest  and  most  efficient
         lifting equipment in the industry.
           “The development of CM Weblok is a
         direct result of us listening to our cus-
         tomers,” said Troy Raines, Chain and
         Rigging Product Engineering Manag-
         er. “A team of CMCO application and
         product  specialists,  product  managers
         and engineers  worked  closely  with  a
         major automotive manufacturer to ad-
         dress  its  safety concerns.  As  a  result,
         Columbus McKinnon  delivered a safe
         and viable solution when our competi-
         tion couldn’t.”
           Made in the USA, CM Weblok As-

         Made of durable forged alloy steel,
         CM Webloks feature greater ductility,
         better fatigue life and higher ductile
