It is sometimes amazing how much frustration and time can be saved when you have the right tool for the job. We found these especially useful for connecting and disconnecting ball links on V-tail slope gliders. You may find these useful as well for your own, "can't quite do it with needle nose" ball links.
In addition to removing and installing ball links these pliers also have two transverse holes across the jaws that are used for changing the length of threaded ball link / push rods. One hole grasps ahold of the ball link the hole grasps the push rods. See pics above.
Designed for ball links 4.8mm - 5mm.
