Small Support Box
4.
Insert the small box in the channel. At this point, do not adhere the small support box to anything.
Place the large support box into the channel and over the top of the small box. Place the CleanCut
Ultra-Low into position and compress the CleanCut Ultra-Low downward to determine the proper
height and placement for the support box structure.
5.
Once the support of the CleanCut Ultra-Low has been achieved, remove the Ultra-Low and mark
both the left and right ends of the small box where the large box is compressed while the boxes are
in the tub opening channel. Once properly marked, remove both support boxes and label the
markings “Left” and “Right” to avoid potential confusion. Uncompress the two support boxes from
one another and begin the process to permanently adhere the boxes in proper position.
6.
Apply adhesive around the perimeter of the large box. Compress the small and large support box
structures back together to the appropriate markings made earlier on the small box. Place the
support structure back into the channel and insert the CleanCut Ultra-Low to verify that proper
placement has been achieved. Secure both sides of the support structure by placing two screws in
each side (Figure 8).
7.
Apply adhesive to the tops of the 2x4’s that are already in place in the channel, if they are needed
for height adjustment and insert the support box structure.
8.
Place the CleanCut Ultra-Low into the channel once more to inspect the fit and position. This is
the final opportunity to make any adjustments if necessary.
9.
Apply adhesive to the top of the large support box. It is recommended that an extra bead of
adhesive be placed on the ends of the large support box as the CleanCut Ultra-Low curves up
toward the ends. Place a substantial bead of adhesive on the top left and right side of the tub where
the CleanCut Ultra-Low will be seated. Adhesive on the top of the tub reinforces the CleanCut Ultra-
Low.
10.
Prior to placing the CleanCut Ultra-Low into the channel, it is necessary to gently pass a low flame
several times along the perimeter of the Ultra-Low where the tub is met. This will help promote
bonding between the CleanCut Ultra-Low and the bathtub where adhesive is applied. Use caution
when using the torch and do not hold heat on one area of the product as it may discolor or melt.
11.
Place the CleanCut Ultra-Low into the channel and gently press into place.
