Handy set of 8 black nylon keepers. Fits soft wire used to make 4-40 pushs rod wire. Black nylon material. Simply bend the end of your pushrod into an "L". Put the L through the servo or control horn. Bend the hand back and clip onto the rod. Simple use, removes and instals quickly. Keeps your push rods from slipping out of the control horns. Light weight, simple and they work great!
