CORNER/ELBOW 90° fitting is used to turn the direction of the gutter in 90 degree. Lines running through the edges ensures strength along with aesthetics. It locks the gutter inside the clip which prevents the edges from flipping out. Use self-screws to fix the gutter. Use silicone sealant inside the slot first and then slide the gutter inside it. Solvent cement is not required.

Installation : Silicone inside slot and screw in slot to gutter.
