Step 1: Track, cont’d
Cut cable access hole in wall
1-3 Using a drill, box cutters and/or a saw, cut a hole at
the base of the wall 4" W x 1½" H (10.1 cm x 3.8 cm).
If there is a metal base stud, use a hand saw or tin
snips to cut it at both edges of the hole and bend
it back into the hole so that the stud lies flat on the
floor. (Use a file to remove any jagged edges that
might damage cables.)
The hole will eventually be covered by the
baseboard, so it does not have to be perfect.

of the wall and mark where the AVTrac will abut the
wall.
Cut aluminum base track

length. The track should run up to but not enter the
hole in the wall.
