Support Box Structure Installation
Once the CleanCut Ultra-Low has been cut and a satisfactory fit into the tub opening is
achieved, it will be necessary to assemble the support box structure to provide support to the
CleanCut Ultra-Low. An example of the CleanCut Ultra-Low and the support box structure is
illustrated in Figure 6.
The CleanCut Support box structure consists of one small and one large support box. The large
support box will compress over the top of the small box to the necessary height to provide support to
the CleanCut Ultra-Low.
It is important to understand that each tub has variations and modifications may be
necessary in the field. For fiberglass and other types of tubs, it may be necessary to adjust
the installation of the support boxes based on the framing or support material present on
the inside channel of the tub. For example, you may only need to use one of the support
box structures based on the height of the bathtub.
1.
It may be necessary to adjust the support box structure according to the conditions present during
your installation. For example, for wooden sub-floors, begin by screwing or adhering with included
adhesive a treated 2x4 directly to the sub-floor to serve as a base for the support structure. For
concrete floors, a treated 2x4 is adhered directly to the concrete floor with adhesive. The 2x4 might
need to be cut into several sections if there is a support brace in the cut-out channel.
2.
Build the support box structure to appropriate height. If working with a concrete sub-floor,
thoroughly inspect and clean the floor in the tub cut-out channel prior to securing the treated
2x4. Remove any materials from the concrete that may cause an uneven surface. Apply
adhesive directly to the concrete floor. Insert the 2x4s and thoroughly spread the adhesive on
the concrete.
3.
Prior to inserting the small support box, it is first necessary to secure a 22
½
” long 2x4 into the
channel of the small support box. Place a bead of adhesive around the inside of the support box
and insert the 2x4. Place several screws into the small support box to properly affix the 2x4 into
proper position (Figure 7).
