Preparation (cont.)
NOTE: The following steps assume 2x4 stud framing is nominal
3-1/2" (8.9cm) x 1-1/2" (3.8cm). Make appropriate rip cut
modifications as necessary for other sized lumber.
Cut two 2x4 support studs to 36" (91.4cm). Rip cut these support
studs so they are 2-3/4" (7cm) deep.
Measure and cut a 1-1/2" (3.8cm) x 9-1/4" (23.5cm) notch in each
support stud so the bottom of the notch is 23-7/8" (60.6cm) from the
bottom of each support stud.
Position the support studs so a 3/4" (1.9cm) offset exists between
the front edge of the stud framing and the support studs.
Use nails or screws (not provided) of sufficient size and quantity,
and securely fasten the support studs to the stud framing. Space the
fasteners carefully in rows, and include a row to within 1" (2.5cm) of
both the top and bottom of the notch.
Measure and cut a piece of 2x10 to fit securely into the notch in the
support studs. Cut the 2x10 so it extends to both stud frame
sections, as shown. Temporarily fit the 2x10 into the notch.
Measure, level, and draw a pencil line across the 2x10 with a pencil
at a of height 30-3/4" (78.1cm) from the finished floor. Mark two
bolt hole locations 7-7/16" (18.9cm) apart on the 2x10 pencil line.
Remove the 2x10 from the support studs, and use a 1/2" drill to
carefully drill through the 2x10 at the marked bolt hole locations.
Fit the threaded inserts into the bolt holes in the 2x10 from the front.
Assemble the fender washers to the bolts, and thread the bolts into
the threaded inserts from the back. Securely wrench tighten the bolts
to the threaded inserts.
Fit the 2x10 assembly into the notches in the support studs so the
bolt shanks face outward. Use minimum 2-1/2" (6.4cm) wood
screws (not provided) to secure the 2x10 to the support studs. Use
four wood screws in each end, and space the screws no more than
2-1/2" (6.4cm) apart.
Use wood screws (not provided) of sufficient size and quantity to
securely fasten the plywood to the support studs.
Install the water supply and drain lines according to the roughing-in
information.
Install the wallboard and finished wall materials according to the
established installation procedures.
