Often times chain is used to rig various pieces of the set, lighting,
or audio equipment. It is important to note that only welded-link steel
chain should be used to bear loads. Many types of chain are available
with unwelded links, but these should be avoided when rigging. To
connect pieces of chain together, it is common to use what are called
rapid links (or QuickLinks, which is a trade name).
Rapid links look like a link of chain with a threaded segment. A nut
can be unscrewed, providing an opening for chain to be inserted into
the link. Once the chain has been inserted, the nut can be tightened,
providing a link capable of bearing weight. Rapid links carry load
capacity ratings stamped on them. These capacities, as well as those
of the chain being used should always be taken into consideration.
