The replacement retaining clip snaps behind the collar on the screw drive connection point. This allows the 3 piece screw drive sections to stay together as the screw turns. Used with most Genie residential screw drive models ever made. The 19807A04.S is for the Clip part only and does not include the Collar. If you also need the Collar to go with the Clip, you will want to add part 19806A04.S to your order.
