Anchor fitting for securing loads to retainer track

An anchor fitting has flat surfaced pads with shoulders extending therefrom and a post portion extending along an axis substantially normal to the flat surfaces of the pads. A fastening device is provided on the post for anchoring a load to a track on which the fitting is removably mounted. The device further includes a screw adjustable plunger and clamp member which can be adjustably positioned by the screw along an axis substantially normal to the flat surfaces of the pads. The fitting is removably retained in a selected position along a slotted track, having a plurality of notched portions separated by narrow neck portions formed by flanges, with the shoulders of the pads and the track slots underneath the flanges and with the plunger lowered by the screw so that it is seated in one of the notched portions of the track with a clamping shoulder portion of the plunger-clamp unit in tight engagement with the top surface of the track. This provides a tight, rattle-proof joinder between the fitting and the track.
