What is the necessary clearance required between the door opening to install a gasket?

The necessary clearance required between the door opening to install a gasket is 15mm. This clearance is crucial because it allows enough space for the gasket to be properly seated and creates an effective seal around the perimeter of the door.

A gasket serves to prevent air and water infiltration, contributing to the overall integrity of the container. A gap that is too large or too small may result in inadequate sealing, leading to moisture entry, which can compromise the cargo. Therefore, a 15mm clearance strikes a balance—enough space to accommodate the gasket without overextending or losing effectiveness, which is why it is considered the standard for such installations.
