Once you know the length remove the existing downspout.
How to attach a rain chain to the gutter.
For the end of the chain where it meets the ground you ve got options.
Decide where the rain chain will be hung and install a downspout outlet in the gutter in the desired location.
Inside the gutter hole insert the gutter bracket or v hook.
If additional length is needed attach a second rain chain and fit to desired length.
Always use extra care when working on a ladder.
A bigger hole needs to be created if the drain hole is too small.
From there attach your rain chain.
Dig a hole slightly wider than the width of your pot and at least 6 deep directly underneath the downspout outlet.
Our rain chain was a little short so we had to loop a piece of copper wire to the last square and then loop it around one of the slots in the catch basin cover plate.
Flip the pot upside.
To connect the chain to the rain gutter locate the rain gutter s drain hole.
Using the hole saw drill a hole in the gutter where you want the rain chain to hang.
Fill the hole with the stone.
Once the hole is located position the gutter chain from the bottom of the hole and push the gutter attachment hangar.
Hang the rain chain.
Release the chain and let it hang from the gutter.
