C-Type Roller Chains
Very same as above except that the side plates are all standard thickness. The strength on the CS Style chains is less than the PT Type but greater compared to the SL variety. Attachments with standard dimen-sions can be used for this series and consequently they’re frequently employed on little materials handling conveyors.
