A Cantilever Arm Prop (IC/PROP) is used where there is a requirement to
increase the effective safe working loads of Single Channel Cantilever Arm
Brackets (IC/CARM/SC) and Double Channel Cantilever Arm Brackets
(IC/CARM/BB). The Cantilever Arm Prop is particularly effective when used
to reinforce cantilever arm brackets carrying heavier duty Speedway
Cable Ladders with their correspondingly higher load bearing capabilities.
