Crosby Chain Connectors

Crosby chain connectors join two pieces of chain, or chain to a hook or ring, without welding. On a tree crew that means building a custom-length skidding chain, repairing a damaged one, or fitting a grab hook to the end.

Using a chain connecting link

A Crosby chain link is the quick fix when a chain is too short, a hook is damaged, or you want a ring on the end for a winch line. Join the pieces, assemble the link per Crosby's instructions, and the chain is back in service.

Match the connector to the chain size and grade so the weakest point is not the link itself.

They are also useful for linking a winch cable eye to a chain, or adding a shortening hook so one chain covers different log sizes. Keep a few links in the truck bin; a broken chain at the start of a big cleanup is a long trip back to the shop.

Clean and lightly oil connectors before storing them so the pins and bodies do not rust together.

Inspection and limits

Check connectors for cracks, wear and spread before each use, and replace any that look stretched. The working load of the assembly is that of its lowest-rated part. Use rated alloy components if the chain will ever be used for lifting, and keep chain work clear of people; a failing chain can whip.

Do not grind, heat or weld connecting links; it changes the steel.

Retire any link that will not assemble cleanly.
