Where two flush cabinet doors meet together and secure with a cupboard latch, you need one elbow catch.Tip (with additional tongue twisting effects): Attach the elbow catch behind the door that holds catch for the cupboard latch. Install it so that the catch mechanism attaches to the bottom of the cabinet shelf. See more items from our Latches And Casters category. Specifications Item # 2949
