摘要

A gasket system (30) has a gasket adapted to be secured about an opening. The gasket includes a mechanism for retaining and sealing a window (14) or the like. The gasket (30) is positioned about the opening such that when the window (14) is positioned within the opening, the window (14) substantially conceals the gasket (30) and is flush at its perimeter with the opening.
