Abstract
Abstract A latch is provided for use on gates to be particularly utilized on livestock enclosures. The latch comprises in combination a latching member and a keeper. The latching member comprises a housing having a latching bolt slidably mounted therein and spring loaded in extended position. A bracket is affixed to the bolt terminating in a finger hold, the bracket and finger hold being entirely recessed within the housing to prevent actuation by animals contained within the enclosure. In an improved version, both ends of the bolt extend out of the housing and the bolt is spring biased to a median position. The bolt may be moved in either direction from the center position by grasping the finger hold, thereby permitting the latch to be used either for right-hand opening or left-hand opening doors.
