150 Crosby part numbers — eye, shank and swivel hooks, Shur-Loc positive locking, and the latch kits to keep them in service.

Read the column, not just the row

The same hook is rated three different ways depending on its material

Crosby publishes carbon, alloy and bronze ratings for one hook size in the same row — and they are not close. A size that carries 1 ton in alloy carries 3/4 ton in carbon and 1/2 ton in bronze. The stock numbers differ too, so check which column you are reading and order against that part number, not the size.

If you are replacing a hook already in service and aren’t certain what it is, send us the Hook ID Code stamped on it. That identifies it exactly.

A latch is not load bearing

It keeps the sling from jumping out of the throat. It carries no load and is not a substitute for a shackle or a locking hook.

Shur-Loc when it must not release

A positive locking latch stays shut until deliberately opened. Worth it where an unloaded hook could be bumped and shed the rigging.

Bearings for loaded rotation

A plain swivel is for positioning before the lift. Only a bearing-equipped swivel is intended to rotate under load.

When to retire one

A stretched hook doesn't go back in service

A hook that has been overloaded opens at the throat, and a hook that has started to open has already been loaded past its design. Crosby publishes the throat dimension for every size — that’s the number to measure against, along with twist, wear at the saddle, and cracks.

Hooks are never repaired by heating and closing them. That destroys the heat treatment and the rating goes with it.

Keep them running

Latch kits are cheaper than hooks

A missing or broken latch is the most common reason a good hook gets pulled from service. The kits above fit the current Crosby hooks and take a couple of minutes to fit — and a hook with no latch fails an inspection.

Tell us the hook code and we’ll send the right kit. There are two S-4320 kits covering different hook generations, so the code matters.
