Perform inspection as follows:  1.  Lay the riser to be inspected face up on a smooth flat surface. Flip the smallest metal ring (No. 3) up  toward the top of the riser and then push down on it to firmly seat it in the webbing, securing it to the  riser. The range of allowable relationships between the No. 3 ring and the grommet is illustrated  below.  2.  If the riser is serviceable up to this point, flip the No. 3 ring down toward the bottom of the riser. Push  down the No. 2 and No. 3 rings (the next larger ring) to firmly seat them in the webbing, securing  them to the riser. The range of allowable relationships between the No. 3 and No. 2 rings is illustrated  below. The riser to be inspected must now be properly assembled to a harness to complete the  inspection.  Repetitive use of the rings in the same position may cause  elongation. This will prevent the rings from releasing.  3.  Rotate the small and large ring and visually check for deformed rings.
