WARNING
Do not install the product in places where water
may be splashed over the product or in humid
places, including outdoor and in a bathroom.
Doing so could cause the functions of the movable handrail to be
damaged and may result in injury.
When the product is used in wet areas such
as a restroom, be sure to apply sealant
around the mounting holes.
If sealant is not applied, water may enter the back of the wall
and cause the product to come off or the wall to collapse,
which could result in user’s fall and injury.
Be sure to use TOTO-designated xing
brackets.
If TOTO-designated xing brackets are not used, the
handrail may come off or the wall may collapse, which could
result in user’s fall and injury.
Make sure that the base has sufcient
thickness and is reinforced, and install the
handrail by the specied installation method.
If the base does not have sufcient thickness or is not
reinforced, and if you do not follow the specied installation
method for each base, the handrail may come off or the wall
may collapse, which could result in user’s fall and injury.
Make sure that the handrail has no backlash
after the installation is complete.
If the handrail has backlash, it may come off or the wall may
collapse, which could result in user’s fall and injury.
Anyone other than service engineers must not
disassemble, repair, or modify the product.
Failure to observe this warning could cause a user to fall due to the
damage or coming-off of the handrail and may result in injury.
Be sure to install this product on a strong wall
or building structure.
If the product is installed directly on a wall that is not strong enough,
including a soil wall and a gypsum board wall, it may come off or the
wall may collapse, which could result in user’s fall and injury.

●Make sure that the wall where the handrail is attached is strong enough.
●Select an appropriate installation method depending on the building
structure.
As the part number of the handrail and that of the wall-xing bracket are different,
please place an order for the xing brackets separately depending on the wall
structure. One xing bracket is required for one handrail. See “ Fixing Brackets
(Optional Parts)” for the required number of xing bracket sets.
*For xing methods not shown in this manual, contact TOTO’s branch ofce, branch
shop, or sales ofce.
●Make sure that there is no obstacle in the handrail moving area .
See “ Completion Drawing” for the moving area.
●See the catalogue, etc. for the handrail installation position.
●Check the functions of the ip-up type after installation, not before
installation.
The ip-up type fullls its functions only after it is installed on a wall, so if you move
the grip bar without attaching the handrail to the wall, you may feel it heavy.
●If the resin coating type or combination type grip bar gets scratched on
its surface, it cannot be repaired. Therefore, please handle the product
with care.
●As the surface of the resin coating type or combination type grip bar is
made of soft resin, if a tool or the like hits the grip bar, the surface of the
grip bar may get dented. In that case, remedy it by the following procedure.
Apply hot air to the dented portion with a
hair dryer for about 2 or 3 minutes.
*The time to apply hot air varies depending
on the degree of the dent. Remedy it while
checking its recovering condition.
Do not apply hot air to the soft resin on the surface of the resin
coating type or combination type grip bar too long.
Doing so may cause the soft resin portion to burn or change in color.
1. Put the hexagon socket head cap screw (⑤) through the spring washer (④),
the paper holder unit(③), and washer (②) in this order, and then insert the
protruding portion of the washer into the prepared hole in the body.
2. Insert the protruding portion of the face nut (①) into the prepared hole of the
body on the opposite side of the washer (②).

①Screw the hexagon socket head cap
screws (2 pieces) equally and lightly using
the longer side of a hex key (opposite
side size: 2.5 mm) until the screws come
in contact with the wall.
②Change to the shorter side of the hex
key and tighten the screws equally and
rmly. (Additional tightening about 180°
from the state of ①)
Hold the
shorter side
of the hex key
Hold the longer side of
the hex key to
additionally tighten the
screw evenly.
●After installation, make sure that the paper holder unit has been xed rmly.
●Pay attention to the orientations of the assembly parts and their mounting
order. If their orientations or mounting order is incorrect, users of the
handrail may get injured at the corners of the parts.
●Attach the washers and the face nuts in such a way that the curved surfaces
of the washers and face nuts are placed along the curved surface of the grip
bar. If the curved surfaces are not placed properly, the paper holder unit
may have backlash or incline.
●On the handrail with paper holder (T112HP type), be sure to mount the paper
holder unit supplied with the handrail. If the paper holder unit is not mounted,
the handrail may ip up on its own, which could result in user’s injury.
●Use a hex key (opposite side size: 2.5 mm) to screw hexagon socket head
cap screws.
*The nuts are used
for putting a wrench
on them when the
hanger bolts are
screwed in.

Determine the mounting position of the handrail and make prepared holes.
Carry out centering using the paper pattern on the reverse side of the
installation manual when positioning the handrail.
*For how to make holes, see each xing method in “ Mounting the Fixing
Bracket on the Wall.”
*For how to mount the xing bracket, see each xing method in
“ Mounting the Fixing Bracket on the Wall.”
Put the bolts protruding from the nished wall surface through the
handrail support plate and the spring washers, and then tighten them
with the face nuts.

Notes 4 and 5
Note 1: Use a drill that can make prepared holes of φ6 mm and 50 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 not be able to secure the mounting plate securely.
Note 2: In the case of T110D49R, be sure to install it with the indication of “UP” facing
upward on the mounting surface.
Note 3: The embedding length of the anchor bolts in concrete must be 37 mm or more.
Note 4: Adjust the projecting length of the bolts to be between 12 and 18 mm from the
nished wall surface.
Note 5: If the bolts are not long enough, procure M10 continuous-thread studs in the
eld.

①Carry out centering and then make
prepared holes of φ10 mm and 85 mm or
more in depth for anchor bolts.
②Screw the nuts about 2 mm from the
upper ends of the anchor bolts, and then
drive them in the prepared holes lightly.
③Tighten the nuts on the anchor bolt.
(This opens the wedges of the anchor
bolts and prevents the anchor bolts from
coming out.)
④Remove the nuts from the anchor bolts.
⑤Adjust 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.
①In 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 φ11 mm for continuous-thread studs.
③Screw the continuous-thread studs into the bolt holes of the mounting plate and tighten
them with nuts.
④Insert 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.
⑤After finishing the wall, adjust the projecting length of the continuous-thread studs to be
between 12 and 18 mm from the finished wall surface.
