In the previous step, we installed all
standard Main Tees and Cross Tees,
working around a section where a Utility
Circle is specified. This is the open
section in the grid assembly shown here. The Utility Circle assembly consists of one
4-inch Utility Circle and four modified
Cross Tees, factory-cut a couple of inches
shorter than standard Cross Tees. To begin pre-assembly, lay these
components out on a table or other
flat surface.
The Utility Circle is ringed with four clips
that connect with the modified Cross
Tees. These clips operate just like Main
Tee splices. Insert the tab through the slot at the end
of each Modified Cross Tee… …then butt the components together
snugly and bend down the tab for a
tight connection.
In this installation the Utility Circle has been
specified for a location where the intersect-
ing Cross Tees curve down to form a valley.
Note: Utility Circles can also be specified
for intersections that curve up to form a
vault. There are slight differences between
valley and vault Utility Circles. With the Utility Circle and intersecting
Cross Tees connected …
…raise the assembly into place and lock
the Cross Tees into position just like stan-
dard Cross Tees.
