This one came with holes in it for rivets.
Cut holes in gutters.
Then i used a fine tooth metal cutting blade in my jig saw.
This is the thing that connects the gutter and downspout together so it is important that it is placed correctly and securely.
Cut the gutter from the bottom with a fine toothed hacksaw.
Make sure the patch is large enough to overlap the hole by at least 1 in 2 5 cm on all sides.
If the patch isn t already small enough to lay flat against the inside of the gutter and over the hole cut it down to size with your metal snips.
Once you cut the patch it may have sharp corners and edges.
Here you can see the shape of the downspout flange i had.
On the bottom of the gutter itself take a pencil or marker and trace the outline of a sleeve.
Step 1 is to draw the shape of the hole and drill s few holes around that shape.
