of
the enclosure
although it is recommended to keep it as far away from the inside wall as possible.

Once placement has been determined cut the proper size hole.

The Precision Port™ should be
l"
longer than Lv when assembled.

you want to use screws to attach the port to the enclosure use the guide marks
on
the back
of
the outside flare. The screw holes are numbered with a 6
or
8 for the number
of
screws you would like to use.
7. When the length has been achieved the Precision Port™ can
be
glued together using
ordinary ABS adhesive
or
similar type glue. Once pieces are assembled with
ABS adhesive, pieces can not be taken apart.
