US Patent 11788625 Hygienic hole seal

A hole seal is provided that can include a plate having a surface configured to face away from an enclosure wall of an enclosure, and a peripheral extension that is angled away from the surface. The hole seal can include a stud coupled to and extending away from the plate, a gasket, a retaining member configured to engage an enclosure wall of an enclosure opposite the gasket, and a fastener. The fastener is configured to threadingly engage the stud and be advanced along the stud to urge the retaining member against the enclosure wall, thereby urging a peripheral extension of the plate into the gasket, via compression of the gasket against an exterior surface of the enclosure wall.
