Hard-to-find “Securo” Lavatory drain will fit most Crane sinks that have the internal fork in the overflow chamber. Due to their unique drain lifting mechanism, the only thing that will fit Crane sinks is one specifically designed for a Crane fixture. This replacement has been machined from an original for an exact fit, but has the outlet threads changed to work with Modern slip joint nuts. Fork not included. This drain does NOT fit Crane Oxford, Cornate, or Beverly sinks.
