What Is the GK External Fit End Cap?

The GK External Fit End Cap is a stainless steel finishing component designed to cover pipe and post ends by fitting over the outside diameter of the pipe. It is widely used in railing systems, staircases, and architectural metal applications where a clean and professional finish is required.

Unlike internal caps, this model sits externally on the pipe, ensuring quick installation and preserving the inner structure of the tube.
