A gutter end cap is the fitting that attaches to and closes off the end of the gutter.
We carry two different types of end caps for k style gutters; the crimp on end cap and the rivet on end cap.
The crimp on end cap is the contractor standard and is the easiest and fastest to install on to the gutter. It requires the use of a hand tool called the end cap crimper. This installation does not require any fasteners.
The rivet on end cap is free from "crimps" and thus has a clean, and finished appearance. The rivet end cap is attached with rivets, which requires a drill, drill bit, rivet gun, and rivets.
