About hooks(grab hook,slip/sling hook)

Toolee have a number of hooks available for use chains, including the grab hook, the slip/sling hook, the sorting hook, and the choke hook. Other accessories used with chains include oval and round master links, shackles, coupling links, and swivel connectors. Grab hook, slip/sling hooks, and master links are most likely to be used when rigging chains.

Grab hooks and slip/sling hooks are manufactured with two types of ends: the clevis type end and the eye type end. The clevis type end has a pin that slips through the chain and the top of the hook to make the attachment to the chain. The eye type end is attched to the chain by welded link or a connecting link. Each type of end has the same strength rating, when properly insalled and matched to the chain.

The grab hook is designed to hook onto a matched chain between the links. It is normaly attached to the master link, connected to the ends of the chain, or joined to another grab hook with a short piece of chain. Two grab hooks can be used to connect two separate pieces of chain. The grab hook is commonly used to hook back into the chain between the links after wrapping an object, to connect separate pieces of chain, and to permit the rescuer to shorten the chain by hooking back to the grab hook.

SLIP HOOK

The slip/sling hook

is designed with a wider throat, which is the space between the tip and the back of the hook, than the grab hook. This allows items such as webbing, chain, master links, or shackles to be placed on the hook do not slip out when there is no weight holding them in place. The grab hook does need a safety catch.
