In stanchions of the type used for milking and/or feeding but primarily the feeding of cattle, a stanchion structure having vertically-spaced upper and lower horizontal members with swing pipes defining spaced positions for accommodating cattle in spaced, captive relationship and having intermediate vertical support posts, an improved structure is provided employing an extending turn bar having spaced depending posts, detents, or tabs, wherein locking flipper members are pivotally secured to each of the swing pipes so that the individual swing pipes may be selectively opened either individually or in unison to permit free access or egress from the spaced, cattle positions by the cattle and wherein the locking mechanisms are protected by the swing pipe structure so as to inhibit opening of the locking mechanism by cattle. The invention is also directed to a conversion kit for existing stanchion structures to provide for the locking feature in a simple and economically feasible manner.
