Steps​

Step 1: Measure and Mark​

Using your combination square, measure 140 mm along the gutter where the outlet will be installed. Mark this measurement clearly with your pencil.

Place the gutter outlet on the marked area and trace around it to mark the outline of the hole accurately.

Drill holes at the marked positions using the drill to accommodate the rivets.

Step 8: Rivet the Outlet​

Reposition the outlet and secure it in place by installing rivets into the drilled holes.

Step 9: Apply Silicone Sealant​

Apply a generous bead of silicone around the edges of the outlet to create a watertight seal.

Step 10: Smooth the Seal​

Run a damp finger along the silicone bead to smooth it out and ensure complete coverage.
