For colored slate tiles (thick)
●Note 1. Construct the eaves trough so that the rainfall trajectory does not go outside the eaves trough.
2. In snowfall regions, always install snow brackets.
■ Important points for design of “measures against wind”
Important points regarding measures against wind for residential gutters are “distance between the brackets” and “installation
position of the eaves trough”.
Classification of strong wind regions is indicated by (Ministry of Construction Notification) regional coefficients (figure below).
Even within the same region, the strength of the wind will be different close to the coast and inland or at the top and base of
cliffs. It will also vary depending on the shape of the building.
Measures against wind are also necessary in regions that are located in the route of yearly typhoons.
In order to prevent problems caused by the
e wind such as displacement of gutters or twisting of brackets, the “distance
between the brackets” and the “installation
n position of the eaves trough” must be considered according to the region and
building height.
[Wind pressure calculation forr eaves trough]
■Formula for finding wind pressure (Article
e 87 of the
Enforcement Order of the Building Stand
dards Law)
W＝Ｃ×ｄ×A
W : Load on eaves trough (kg)
C : Coefficient (assumed to be 1.5
5 for eaves)
d : Wind pressure per unit area (kg
g/m2)
A : Area of base of eaves trough (m
m2) taking
wind load = Width of base of eaves
trough(m) x Distance between brackets (m)
Classification of
strong wind regions
(regional coefficients)
■Difference in wind pressure calculation due to
building height
・If under16 m ｄ=60√H
・If over 16 m ｄ=1204√H
(H: Height from ground surface (m))
■ (E.g.) For eaves trough AC120
W＝60√16×1.5×0.131×0.6＝28.29Ｋｇ
«Rounded up to 28.3 kg»
H: Height to eaves trough, 16 m
C: 1.5
Width of base of eaves trough: 0.131 m
Distance between brackets: 0.6 m

●Construction procedure and instructions
Use genuine DENKA adhesive (600ZT) inorder to prevent water leakage.
1. Determining location of drop outlets
Hip roof
(Funnel/drain)
○Location of funnel or drain
Gabled roof
2. Procedure for installing eaves trough brackets
●Install brackets on both sides of the eaves.
●Stretch a leveling string along the brackets on
both sides.
●The distance between brackets in normal
regions is 900 mm.
Install brackets at intervals of 450 mm or less in
snowfall regions.
In snowfall regions, install snow brackets on the
roof.
Normal regions, 900 mm

3. Procedure for installing eaves trough
●Cutting eaves trough
Use a hacksaw to cut the eaves trough at a right
angle.
Remove all burrs from the cut surface.
Check
●Hook the eaves trough’s hidden hanger lip
securely onto the edge of the brackets. Then,
push the base of the eaves trough up and fit the
rear mounting ear.
●Check that all of the brackets are fitted into the
eaves trough.
Push up
4. Procedure for installing socket
①Apply two rows of adhesive evenly around the
entire circumference of the inside of the socket.
Apply up to below the mounting ears ensuring
that there are no gaps, particularly at the corners.
②Hook the socket onto the eaves trough’s rear
mounting ear and fit it onto the front mounting ear
by rotating it forwards.
③Slide the socket all the way on.
Location of
adhesive application
※After fitting, carry out sealing
work. Do not apply more
than the standard amount of
adhesive.
4 mm
2 mm
④Set the other eaves trough and, after inserting it
all the way on, carry out sealing work.

5. Procedure for installing expansion socket
①Apply rows of adhesive around the entire circumference
of the eaves trough insertion section of the expansion
socket (slider, cover), ensuring that there are no gaps.

②Install the expansion socket by snapping it onto the rear
side and front side of the eaves trough. Push the eaves
trough all the way into the insertion section.
With temporary fixing tab★

③The temporary fixing tab★ is easily removed by picking
its inside surface with the tip of one’s finger and rotating
it upwards.

※The efficiency of the expansion socket cannot be
maximized unless the eaves trough is connected in the
correct position. Therefore, carry out the connection
work without removing the temporary fixing tab★. (Be
sure to remove the tab after construction).
6. Procedure for installing bend (outer corner) (inner corner)
①Apply rows of adhesive evenly around the entire
circumference of the bend’s joining surface, ensuring that
