7. Center the long block over one of the center punch
marks on the side of the pipe. Align the long block so
that the pressure bolt is directly over the punch mark.
Fasten the block to the pipe by wrapping both chains
around the pipe and fastening the chains to the screw
hooks on the opposite side of the block.

8. Use the wing nuts to tighten the chains on the long block
until the block is tightly secured to the pipe.
IMPORTANT:
Make sure both chains are perpendicular to the bottom of
the block and are not twisted. If the chains are slanted, the
slack may cause the block to move.

9. Position the clamping fixture rails so that the fixed short
block is placed over the remaining center punch mark
on the opposite side of the pipe and the pressure bolt is
directly over the punch mark. Make sure the fixed short
block is not positioned on top of the chains of the long
block. The adjustable short block may be placed on
either side of the long block chains.

10. Wrap one short block chain around the pipe and fasten
the chain to the screw hook on the opposite side of the
block. Repeat this for the other short block.
Note: Make sure the chains on both blocks are on the same
side of the fixture and are opposite the slide rail with the
ruler.

11. Use the screw hooks to tighten the chains on both the
fixed and adjustable short blocks until both blocks are
tightly secured to the pipe.
IMPORTANT:
Make sure the chains are perpendicular to the clamping
fixture and are not twisted. If the chains are slanted, the
slack may cause the fixture to move. Also, the transducer
spacing dimension may change after the transducers are
mounted.
