ABSTRACT:
An entranceway barrier comprises two telescoping L-shaped frame assemblies having a ratcheting locking system that allows the barrier to be quickly inserted in a doorway. A self-locking ratchet mechanism allows the barrier to move outward exerting a securing force against a frame gasket placed in a doorway until the ratchet is manually released. A severable panel slides into a channel and is secured with a gasket channel seal to provide flood protection. Another embodiment comprises two telescoping C-shaped frame assemblies with two panel sections that slide adjacent to each other to provide adjustability.
