2-1. Before Installation
Precautions before installation
●Make sure that the wall where the handrail is attached is strong enough.
●When installing the handrail in combination with a product with a photoelectric sensor,
make sure that the sensor does not detect the handrail .
For the mounting positions of a product with photoelectric sensor and the handrail, see the manuals or
catalogs for products with photoelectric sensor.
●Select an appropriate mounting method depending on the structure of the building .
As the part number of the handrail and those of the wall- (oor-) xing brackets are different, please place an
order for the xing brackets separately depending on the wall structure.
See “ Fixing Brackets (Optional Parts)” for the required number of xing bracket sets.
*For installation methods not shown in this manual, contact TOTO’s branch ofce, branch shop, or sales
ofce.
●See the catalogue, etc. for the handrail installation position.

backlash!
Do not install the product outdoor or in areas that
might be submerged.
Doing so could cause a user to fall due to the damage or coming-off
of the handrail and may result in 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, the handrail may come off or the wall
may collapse, which could result in user’s fall and injury.
Check the installation orientation of the I type handrail for
washing area in bathroom.
If the product is installed in the orientation not shown in the illustration, a part of the body
(neck, etc.) could get caught between the handrail and the wall and may result in injury.
Check the space between the handrail for Japanese-style toilet and its
surrounding xed objects and the installation position of the handrail.
Failure to do so could cause a part of the body (neck, etc.) to get caught
between the handrail and the xed object and may result in 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.
When the product is used in wet areas such as a bathroom,
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.

3-1. Fixing Brackets (Optional Parts)
●If the resin coating 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 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 grip bar too long. Doing so may
cause the soft resin portion to burn or change in color.

*●shows the parts that need to be procured in the eld. “Pipe” indicates metal pipes (φ13.8,
t2). Please purchase them at a hardware store or a home improvement center. Prepare pipes
with an appropriate length considering the thickness of the wall.
*"-" means that it cannot be installed.
Note 1: [GL method] Available only when the thickness of GL (Gypsum Lining) is 50 mm or less.
Note 2: [Concrete block base] Available only when the thickness from the back of the concrete
block to the nished wall surface is 125 mm or less.

Secure at least 120 mm of space
between the handrail and the ush valve.
Install the handrail inside the extension
lines of both sides of the bathtub.

When using bolts
Put the bolt through the spring washer and the washer
according to the order shown in the gure on the right,
and then temporarily fasten the grip bars to each other
with a hexagonal wrench.
①Push the washer (large) into the joint, and then
push the grip bar into the joint.
*Attach the washer (large) in such a way that its
at surface comes into contact with the grip
bar.
②Attach the bolts in the same procedure as that
of "part A in Completion Drawing."
4.
●Because a washer has a at
surface and a curved surface,
place the at surface on the
spring washer side.
If the washer is placed in the
opposite orientation, the
handrail may become loose.
(Washers are not used for
T112CU22.)
●Do not fully tighten the bolts
before mounting the handrail.
If the handrail is mounted after
fully tightening the bolts, you
may fail to install the handrail.
Put the bolt through the spring washer and the
washer according to the order shown in the gure
on the right, and then temporarily fasten the grip
bars to each other with a hexagonal wrench.
①Push the grip bar in such a way that the screw
hole of the grip bar ts the screw hole of the
joint.
②Firmly tighten the set screw with a hexagonal
wrench.

Therefore, be sure to check the wall before
installing the handrail.
③Screw the continuous-thread studs in the
outer bolt holes of the mounting plate to the
