①
Carry out centering and then make
prepared holes of
φ
10 mm and 85 mm or
more in depth for anchor bolts.
②
Screw the nuts about 2 mm from the
upper ends of the anchor bolts, and then
drive them in the prepared holes lightly.
③
Tighten the nuts on the anchor bolt.
(This opens the wedges of the anchor
bolts and prevents the anchor bolts from
coming out.)
④
Remove the nuts from the anchor bolts.
⑤
Adjust the projecting length of the anchor
bolts to be between 12 and 18 mm from
the finished wall surface.
*The nuts of the anchor bolts supplied
with the fixing bracket are not used
when the handrail is mounted.
①
In the case of a wooden base, mount reinforcing wooden blocks that are 50 to 60 mm in
thickness on the handrail mounting area beforehand.
②
Carry out centering and then make through holes of
φ
11 mm for continuous-thread studs.
③
Screw the continuous-thread studs into the bolt holes of the mounting plate and tighten
them with nuts.
④
Insert the continuous-thread studs into the through holes, put the mounting plate on the
back of the wall, and tighten with washers and nuts from the handrail mounting side.
⑤
After finishing the wall, adjust the projecting length of the continuous-thread studs to be
between 12 and 18 mm from the finished wall surface.

Note 1: Use a drill that can make prepared holes of
φ
10 mm and 85 mm or
more in depth in concrete. If the bit size of the drill is too large or if it
has core deviation, you may fail to fix it securely.
Note 2: The embedding length of the anchor bolts in concrete must be 50 mm
or more.
Note 3: Adjust the projecting length of the anchor bolts to be between 12 and
18 mm from the finished wall surface.
Note 1: In the case of a wooden base, mount reinforcing wooden blocks that
are 50 to 60 mm in thickness securely on a strong pillar, etc.
Note 2: In the case of a concrete block base, it is not necessary to fill hollows
with mortar, etc.
Note 3: In the case of T110D49R, be sure to install it with the indication of
“UP” facing upward on the mounting surface.
Note 4: Adjust the projecting length of the continuous-thread studs to be
between 12 and 18 mm from the finished wall surface.
Note 5: If the bolts are not long enough, procure M10 continuous-thread studs
in the field.
