①
Mount reinforcing wooden blocks that
are 60 mm or more in thickness on the
handrail mounting area beforehand.
②
Carry out centering and then make
prepared holes
φ
8.5 mm for hanger
bolts.
(In the case of a tile wall, make through
holes of
φ
11 to 13 mm only in the tile
area.)
③
Fix using the nuts (2 pieces) as a double
nut, which come with the hanger bolts.
(See the figure below.)
④
Turn the double nuts fixed in
③
using a
tool, and screw the hanger bolts into the
prepared holes.
⑤
Adjust the projecting length of the bolts
to be between 12 and 18 mm from the
finished wall surface.
⑥
Remove the double nuts.
①
While carrying out centering, fix the
mounting plate to the reinforcing
light-gauge steel frame (t 2.3 mm or
more) by welding.
②
Screw the continuous-thread studs into
the holes of the mounting plate, adjust
their projecting length to be between 12
and 18 mm from the finished wall
surface, and tighten from the back of
the wall with nuts.
③
Finish the wall.

*You cannot adjust the
mounting position of the
handrail after finishing the wall.
Note 1: Be sure to mount reinforcing wooden blocks that are 60 mm or more
in thickness.
Note 2: Use a drill that can make prepared holes of
φ
8.5 mm in the
reinforcing wooden blocks. If the bit size of the drill is too large or if it
has core deviation, you may fail to fix it securely.
Note 3: Be sure to use the nuts (2 pieces) as a double nut to put the hanger
bolt in the wall. If face nuts are used, the heads of the face nuts may
be damaged.
Note 4: Adjust the projecting length of the hanger bolts to be between 12 and
18 mm from the finished wall surface.
Note 1: Use reinforcing light-gauge steel frames that are t 2.3 mm or more.
Note 2: Adjust the projecting length of the continuous-thread studs to be
between 12 and 18 mm from the finished wall surface.
Note 3: In the case of T110D49R, be sure to install it with the indication of
“UP” facing upward on the mounting surface.
