gutters and downspouts
87
Using a hacksaw or a power saw,
cut the gutter to the proper length.
Install end caps by first applying a
bead of sealant to the ends of the
gutter and then rivet the end caps
into place with aluminum rivets.
(Fig. 1)
Using aluminum blind rivets, attach
downspout clips to the back of the
gutter downspouts approximately
every eight feet. (Fig. 2)
Cut a hole in the gutter to accommo-
date the eave tube (where the gutter
attaches to the downspout). Be sure
to allow sufficient clearance on all
sides for the flange of the eave tube.
(Fig. 3)
Apply a bead of gutterseal and rivet
the eave tube in place.
Assembling Miters
Occasionally, it will be necessary
to miter gutter around an inside or
outside corner. Determine the proper
point on the gutter to be mitered and
cut both left and right-hand gutter
lengths at an approximate 45° angle
for both inside and outside miters.
Seal and rivet miter to one section
of gutter and then position gutters
onto hangers. Seal and attach miter
to second gutter. (Fig. 4)
NOTE: Most outside or inside
corners are 90° angles.
The second option is to install both
gutter sections onto the hangers.
The strip miter can then be placed
over the top of the mitered joint
between the two pieces of gutter
Using gutterseal, seal and pop rivet
the strip miter to the two pieces of
gutter and then seal all rivet heads
and joints on the interior of the
gutter.
Installation of
Expansion Joints
To join gutter sections together,
modify one end by notching the top
front bead and rear hook edge 2.
Overlap sections 1-1/2" as shown.
Apply sealant to all laps and rivet.
On long runs over 37 ' , or where
there is no room for expansion,
apply expansion joint. Notch gutter
as shown and apply a sealant under
both sides of the joint. Center the
expansion joint over the 1-1/ 2"
metal lap and rivet. (Fig. 5)
Seamless Gutter Limitations
and Best Practices
•Hiddenandziphangersallow
more expansion on longer runs
when the front moves freely.
•Seamlessguttersarenot
warranted for runs greater than
50'. For applications that exceed
50' (especially at 40°F or lower,
use 0.032 coil in lengths of less
than 50', butted together with
endcaps.
