ABSTRACT:
A means of securing a panel in an opening in a wall or the like, comprising an assembly having a body fixed to the wall adjacent to the opening. A sliding member in the body is positioned to slide over the panel, and is provided with a threaded locking member to be brought into engagement with the surface of the panel in a direction substantially normal thereto. A friction-inducing member is provided to co-operate with the sliding member and the body to reduce the tendency of the sliding member to shift when the threaded member is not engaged with the panel.
