Abstract: An anchor fitting for removably securing a load to a slotted track member at preselected positions therealong, such as for example for securing cargo, passenger seats, etc. in various positions along the floor of an aircraft. The fitting has flat surface pads with shoulders extending therefrom and a post portion extending along an axis substantially normal to the flat surfaces of the pads. A latching plunger is slidably mounted on the post portion for motion along the longitudinal axis thereof. The fitting is removably retained in the track which has a plurality of notched portions separated by narrow neck portions with the plunger member seated in one of the notched portions of the track and with the surface pad shoulders of the fitting beneath the flanges. A clamp member having a U-shaped portion which slidably fits over the body of the fitting has flanges which extend outwardly therefrom.
