3.4.2 Installation- the Catenary Sag

The function of the catenary is to allow a place for excess chain to accumulate.
Rex® TableTop® chains should never be run tight.

The catenary sag should be measured when running with product.

If the catenary sag is excessive or increased due to normal wear, it should be
adjusted by removing links to obtain the proper sag.
3.4.3 Installation/Disassembly-Chain
Connect the chain/One piece Chains with Round Pins

To connect each 10 ft. section, start by positioning the connecting pin into either
one of the double eyes in the appropriate end link. Position the single eye of the
other end link between the double eyes. Then drive pin through the single eye
and into the adjacent double eye, using a drift punch and hammer, until
connecting pin is centered in the link.
CAUTION
Minor or moderate injury will or could occur
The chain should be hand tight when installed. Chain should never be over tensioned.

When installing the last section, separate the chain to required length using a drift
punch and hammer to drive appropriate connecting pin out of chain. Make final
connection to complete the chain loop.
3.4.4 Connect the chain / One Piece Chains with Style D Pins.

To connect each 10 ft. section, start by positioning the connection pin into either

flat of the pin to match up with the flat on the link hole. Position the single eye of
the other end link between the double eyes. Then drive pin through the single eye
and into the adjacent double eye, using a drift punch and hammer, until
connecting pin is centered in the link. When installing the last section, separate
the chain to required length using a drift punch and hammer to drive appropriate
connecting pin out of chain. Make final connection to complete the chain loop.
