Product Overview

This rubber plug for shipping container ISO hole (also called rubber cover, hole rubber plug, or shipping plug) is a specialized sealing accessory designed to seal standard ISO holes on container corner castings and bases.

Why You Need Rubber Cover

The open ISO holes in the container corners are the primary weak points. Without proper rubber covers for these holes, moisture, salt spray, dirt, pests, and debris can enter. This leads to rapid corrosion inside the steel corner fittings, compromising the container’s structural integrity and potentially damaging stored cargo.

Installing this rubber cover effectively blocks moisture ingress, extending the service life of containers and reducing maintenance costs. It serves as a simple, low-cost, and highly effective container protection solution suitable for ports, yards, factories, construction sites, and similar environments.
