Attaching the Fixtures

This section shows how to attach and secure the mounting base, chains,

align the two mounting bases by leveling, install the sensor heads, turn on

the sensor heads, and center the lasers on their targets.

Attaching Chain to the Mounting Base

Select the chain tightener of choice. The left photograph shows a standard

hex nut which should be tightened with a 9/16 inch wrench. The right pho-

tograph shows a knurled nut which can be tightened by hand. The hex nut

mechanism provides a more stable, versatile mounting while the knurled

nut is more convenient. Use each nut as shown.

These photographs show how the chain assembly should be slipped into

the mounting base. Hold the chain out away from the base and slip the cyl-

inder into its cradle. To ensure maximum tightening range, each nut should

be ﬂush with the end of the tightening bolt.
