摘要： A hook member for securing and snugging a door of a structure such as a barn is provided with a cam lever which may be manually rotated after the hook member is engaged with a latch bar on the door to move the hook member longitudinally away from the door and thus pull the door snugly against the portion of the structure on which the hook member is mounted. The cam hooks of the invention may be mounted inside a building to snug the rear edge portions of single or double sliding doors against the building wall, or to snug the front edge portion of a single sliding door or of a hinged door against the jamb; and may also be used to snug the forward edges of a pair of double sliding doors together either from the inside or from the outside.
