3 Before replacing the tub track, force a slight
downward bow in the middle of the extrusion. This will
ensure that the track fits tight to the tub in the center. Run
two beads of silicone inside the pencil marks on the threshold.
Also, apply a liberal amount of silicone where the threshold
and wall meet on both sides. Apply enough to fill the void of
the bottom track.
Place the tub track in the exact position marked in Step #2
and seat it firmly into the silicone. Once the track is in place,
run a bead across the top the track where it meets the wall.
NOTE: Improper silicone will result in leaks.
1 Measure the wall to wall opening at the center
of the threshold. Cut the bottom track [A] 1/16” short of
that dimension. An inexpensive miter box (available at
a hardware store) will help you get a clean, square cut.
Place the bottom track in the desired position of the
threshold, typically in the center, with the raised edge
to the exterior. (see illustration) It may be necessary to
file a radius on the corners of the bottom track and wall
jambs to match the corners of the opening. Lightly mark
its location with a pencil.
Press both wall jambs [B] into position over the tub track.
It is not necessary to trim the vinyl silencer back for the
wall jambs. The wall jamb should cut through it for you.
Masking tape can be used to hold the parts in place temporarily.
2 Using a level, plumb one wall jamb and mark the three
hole locations on the wall with a pencil. Repeat this step for
the other wall jamb. Remove all parts and drill the holes.
Tile or marble walls:
Drill 3/16” diameter holes into the walls and insert the
plastic wall anchors [C].
Fiberglass or acrylic units can be done two different ways:
If the walls are not reinforced, drill 3/16” diameter holes
and insert the plastic wall anchors. (Toggle bolts may
be used instead but they are not provided).
If the walls are reinforced, only drill 1/8” diameter holes.
CAUTION: The bottom track should never be screwed to the threshold.
